scorpiosonic Posted July 5, 2014 #54 Share Posted July 5, 2014 1: The asteroid is ONLY 580 meters wide. 2: NASA have a mission to send a craft there 2016 "The asteroid 1999 RQ36 is the target of a new unmanned spacecraft, which NASA plans to launch in 2016 to collect a sample from the space rock and return it to Earth by 2023" http://www.space.com...-1999-rq36.html . 1999 RQ36, diameter 200-500 meters, performs 1 turn-a-round in 4,5hrs so there are low centrifugal forces.* *(This statement is not valid for any fake vids showing alien bases // burger kings // towers // glas domes // pyramids // mother ships on celestial objects.) Hi Bee, Since Sky Scanner can't post links very easily right now, I'll back him up. 1999 RQ36, also known as Bennu, was indeed about 160 million miles away from Earth on June 29, when these images were supposedly taken: Source: JPL Small Body Database http://ssd.jpl.nasa.gov/sbdb.cgi#top NEOSSat is a Canadian satelite with a small 15 cm telescope (link). There is absolutely no way this satellite could have taken those images at that distance. This is all just another fake, as I think you suspected. Y'all did much better research than the website did! Not really psyche, that's a small polarised faction of this subject, played out on internet forums. I chat to plenty of interesting people with plenty of interesting ideas on this subject. If i'm chatting to someone about this at an astro event, or through other means I don't expect them to back-up their thoughts with a link or peer reviewed article, we're just throwing ideas about on a subject that is hard to pin down...I like to do the same on forums when the conversation allows. I just find the subject far to interesting to waste much time on the soap opera side of it - as they say though 'to each their own'. Another crackpot 'theory' completely lacking in credibility. (or attempting to be credible ) If they are going to photoshop something like this, maybe start w/ a pic of "Planet X"...there are many such small objects orbiting Neptune, Pluto, and beyond, etc. and at least SAY they used their 'secret new-and-improved and larger' telescope.

sinewave Posted July 5, 2014 #58 Share Posted July 5, 2014 To me the "pyramid" seems to be made of different material than the rest of the asteroid and has four sides with straight edged corners. Interestingly after googling the named asteroid i found this information as well. When it comes to visiting asteroids, NASA doesn't pick run-of-the-mill space rocks. The target of NASA's latest asteroid mission is not only thought to be rich in the building blocks of life, it also has a chance — although a remote one — of threatening Earth in the year 2182. The asteroid 1999 RQ36 is the target of a new unmanned spacecraft, which NASA plans to launch in 2016 to collect a sample from the space rock and return it to Earth by 2023. The mission's leaders spent a long time surveying possible destinations for the mission, and finally settled on 1999 RQ36. NASA calls the mission OSIRIS-Rex, which is short for Origins-Spectral Interpretation-Resource Identification-Security-Regolith Explorer. Link You are correct about there being different materials. Asteroids are not usually homogeneous but conglomerations of random debris. Link to comment Share on other sites More sharing options...

sinewave Posted July 5, 2014 #62 Share Posted July 5, 2014 are you saying random debris gets stuck together in space...and makes asteroids? . Yes, having mass they all have gravity so they tend to attract each other. They also collide and the bits coalesce to form larger asteroids. There is at least one that is perfectly round.

Sundew Posted July 5, 2014 #64 Share Posted July 5, 2014 We now live in an age where virtually (no pun intended) any image or video can be altered. That does not mean necessarily that such manipulation has reached the point where an expert, or even someone fairly familiar with such technology cannot spot the deception. But what it does mean is that genuine phenomena are often lumped in with all the nonsense, or that those unfamiliar with such manipulation can easily be taken in, making it increasingly difficult to tell fact from fiction, the genuine from the bogus. There are still real mysteries in this universe to be studied, and it does a disservice to those seeking to discover them. Link to comment Share on other sites More sharing options...

It helps to understand that asteroids are not exactly as they are depicted in movies. They don't move in tight packs. There is actually a lot of space between them. Having the largest local mass they tend to attract smaller objects that are added to main mass to make it larger over time. It is a bit like magnets picking up iron filings. After a few billion years of wandering the solar system, they tend to pickup rather a lot of debris that becomes surface features. Sometimes they are made smaller by impacts. It depends on the circumstances. Edited July 5, 2014 by sinewave Link to comment Share on other sites More sharing options...

I mean where does that growth end...do they just get bigger and bigger till they are ginormous..? ????? There is a dynamic at work. They all attract other debris so they all grow over time, albeit very slowly. Some get large enough to establish spherical shapes. Collisions can break them up, as you surmised. Those collisions can create asteroids that contain parts of the parent asteroids. The one in question could be the product of two or more different asteroids. Ceres is roughly a third the size of our moon and is round. http://en.wikipedia.org/wiki/Ceres_(dwarf_planet) Edited July 5, 2014 by sinewave 1 Link to comment Share on other sites More sharing options...
bee Posted July 5, 2014 #68 Share Posted July 5, 2014 . ok...all below is quoting from link... http://www.universet...eroids-made-of/ What are asteroids made of? That is a very interesting question and if you are asking that it shows that you have a very keen and curious mind. Asteroids are made of different minerals and substances. Their composition depends on which planet they may have originated from. Many asteroids are the result of larger asteroids hitting planets or each other during the fiery beginnings of the Solar System. The chemical reactions that they have undergone over the millenia also effects their composition. The asteroids that are nearest the Sun are mostly made of carbon while the ones further away are made up of silicate rock. The metallic asteroids are composed of up to 80% iron and 20% a mixture of nickel, iridium, palladium, platinum, gold, and other precious metals. There are those few that are made up of half silicate and half metallic What are asteroids made of? Well, that depends on which class they are. There are four major classes of asteroids: C type, D type, S type, and V type. Each has a different composition and position in the universe. C type are found in the outer areas of the main belt and are darker and more carbonaceous the the S type. S type are found in the inner area of the main belt, closer to Mars, and are composed of mostly stone and iron. D type are also known as the Trojan asteroids of Jupiter and are dark and carbonaceous in nature. V type are a far out group. They hang out between the orbits of Jupiter and Uranus and are made of igneous, eruptive materials. Now that you know what are asteroids made of, here a couple of interesting facts about them.: All asteroids are covered in space dust called regolith. This dust is usually a rocky rubble more than dust. It is the result of the constant collisions the asteroids undergo in space. The larger asteroid usually wins n these collisions and ends up covered in the rubble of the loser. Some asteroids have moons of their own. The spacecraft Galileo first discovered an asteroid with a moon in 1993 when it flew by the asteroid 243 Ida. Asteroids like to group together in the solar system. There are four main groups of asteroids. There are the main belt, the Kuipers, the Trojans, and the scattered disc. Theoretically there is a fifth group called the Oort cloud, but it is too far out into space to be studied. Near Earth asteroids are monitored by NASA’a Sentry and NEAT programs. Hopefully this article has given you the information that you wanted about what are asteroids made of and a few interesting facts that you can impress your friends with. The more that asteroids are studied, the more that astronomers find that they need to learn about them. Here on Universe Today we have some good articles on interesting facts about asteroids and what the difference is between and asteroids and comets. Astronomy Cast has a great episode on sky surveys. Reference: NASA end of quote... sinewave you must be referring to the underlined above...the regolith....the space dust / rubble.. I'm not sure how much rubble would need to stick to an asteroid to make it significantly bigger... so I'm still not satisfied.... but I don't have the time now to look into it more...so it will have to wait for another time...

Bigger is a relative term, of course. As I mentioned, growth by gathering dust and larger material from other asteroids is a slow process. They are not going to get gigantic, just slightly larger.

JesseCuster Posted July 5, 2014 #72 Share Posted July 5, 2014 They are not going to get gigantic, just slightly larger. Depends on the situation. If there's enough loose matter around like in the early system they sometimes get gigantic indeed, forming planets thousands of miles wide.Sometimes gravity causes enough matter to coalesce together to create giant nuclear power balls of plasma millions of miles in diameter. 1 Link to comment Share on other sites More sharing options...
