It means that a single year for this hot Jupiter – a gas giant similar in size and composition to Jupiter in our own solar system – passes in less than a day of Earth time.

MissJatti Posted February 23, 2020 #2 Share Posted February 23, 2020 It takes 18 (Earth) hours, to go around the sun and back again. (Orbit). Astonishing for a planet the size and mass of Jupiter. I wonder how many minutes is 1 full day on this planet lol Link to comment Share on other sites More sharing options...

For clarity, it's not orbiting the sun, it's orbiting a dwarf star called NGTS-10. This star is much smaller and a bit cooler than the sun. 1 hour ago, MissJatti said: I wonder how many minutes is 1 full day on this planet lol From the article: Quote The planet is likely tidally locked so one side of the planet is constantly facing the star So it's day is probably the same length is it's year, 18 hours.
