What did Rosetta find on the comet?
Rosetta and its lander, Philae, made numerous discoveries while at the comet. Those included finding out that the type of water that makes up 67P has different isotope (element type) ratios than the water on Earth. This suggests that comets similar to 67P were not responsible for bringing oceans to our own planet.
Did the Rosetta mission land on a comet?
The Rosetta spacecraft followed a 10-year mission to catch a comet and land a probe on it. Launched in 2004, the spacecraft arrived at its target, Comet 67P/Churyumov-Gerasimenko, on Aug. 6, 2014. The mission included the Philae lander, which made the first touchdown on the comet.
Can you stand on an asteroid?
That asteroid would have a surface gravity less than 1 millionth that of Earth, and an escape velocity of only 5 cm/s. When you lift your foot to make a step, you are already moving upwards fast enough to leave the asteroid, and you will never get back down to the surface. You can not walk on such an object.

What is the Rosetta spacecraft?
The two-part Rosetta spacecraft is designed to orbit and land on the Comet 67P/Churyumov-Gerasimenko in November 2014. See how the Rosetta spacecraft works in this Space.com infographic. (Image credit: by Karl Tate, Infographics Artist)
How many times did Rosetta fly by Mars and Earth?
Along with Philae, its lander module, Rosetta performed a detailed study of comet 67P/Churyumov–Gerasimenko (67P). During its journey to the comet, the spacecraft flew three times by Earth, by Mars, and the asteroids 21 Lutetia and 2867 Šteins.
