Can you land a spacecraft on a comet?
Having far smaller mass than the Earth, the gravity on the surface of a comet is much lower than on Earth, and so landing in the traditional sense would not be possible as you would bounce off the surface.
What is the only spacecraft to land on a comet?
Rosetta spacecraft
Philae (/ˈfaɪliː/ or /ˈfiːleɪ/) is a robotic European Space Agency lander that accompanied the Rosetta spacecraft until it separated to land on comet 67P/Churyumov–Gerasimenko, ten years and eight months after departing Earth….Philae (spacecraft)

What would it be like to land on a comet?
If you were on a comet when it had a coma, the cloud would likely obscure the stars. And during the day (a full day on Halley’s Comet is between 2.2 and 7.4 Earth days), your field of view would be filled with diffuse light, similar to what you’d see when standing in a deep fog, Moorhead said.
How big is the Rosetta comet?
1.2427 mi

Where is Rosetta now?
Rosetta monitored comet 67P/Churyumov-Gerasimenko’s evolution during its closest approach to the Sun and beyond. The mission ended with a controlled impact on the comet on Sept. 30, 2016. Both Rosetta and Philae remain on the surface of the comet.
What did Rosetta find?
Besides collecting a vast amount of data on the properties of the comet, including its interior, surface and surrounding gas, dust, and plasma, Rosetta’s key findings included the discovery of water vapor in comet 67P/G-C (vapor that is significantly different from that found on Earth), the detection of both molecular …
Can you jump off a comet?
So the answer is: Yes. A human astronaut could probably just jump off a spacecraft and land on a comet.
Do Comets have gravity?
The reason behind this is simple: Comets aren’t terribly big—67P is roughly four kilometers across and has a mass considerably less than a typical Rocky Mountain. This makes the force of gravity on the comet pretty weak, barely enough to hold it together.
Has anyone landed on a comet?
On November 14, 2014, the Philae lander accomplished the first ever soft landing of a human-made spacecraft on the surface of a comet—a never before accomplished feat, and one that was considered very ambitious and risky at the time.
