Will asteroid Apophis hit Earth in 2036 ?

Scientists have proposed a spacecraft that could prevent an asteroid from colliding with the Earth.

A small spacecraft with a solar sail placed in a retrograde orbit could change the path of a large asteroid if it collides with it far enough in advance. The project was devised as an answer to the possible threat of the massive asteroid Apophis which is thought to have a small chance of hitting the planet in 2036.

"Shengping Gong, Junfeng Li, and Xiangyuan Zeng of Tsinghua University in Beijing, China, have published an article in Research in Astronomy and Astrophysics (RAA), proposing to place a small spacecraft with a solar sail into a retrograde orbit to prevent an asteroid from colliding with the Earth in 2036."

The subtlety of Chinese culture, as opposed to Texas-style "Big-Is-Best". Chinese propose using a tiny 10 kg item as opposed to NASA's gigantic "asteroid tractor", 20-ton spacecraft. I say we nuke that asteroid. USA! USA! USA!

hmm well we have escaped close colision many times so mabye this time it will hit? in reply to the above post well thats a typical american for you always thinks "nuking it" will solve all and every problem. now how exactly could nuking it solve famines global warming droughts and lack of oxegen from over deforestation

I'm no scientist, but if we all join hands and sing a song like they did down in Who-ville, we can repel the object with our love and understandng, its Apophis is nothing more than a Grinch.....a Grinch that could wipe out all life, but a Grinch none the less, lol. im pretty sure the article said enough to destroy a city or two or cause a tsunami not wipe out all life not even the dino age asteroid did that
