The gravitational acceleration on the surface of Comet 67P/Churyumov-Gerasimenko is extremely weak, estimated to be around 10⁻⁴ m/s².

Here's why:

* Low Mass: Comets are relatively small and have very little mass.

* Low Density: Comets are primarily composed of ice and dust, making them very porous and low in density.

To put this in perspective:

* The gravitational acceleration on Earth is about 9.81 m/s².

* That means the gravity on Comet 67P is about 100,000 times weaker than on Earth.

This weak gravity is one reason why comets have such irregular shapes and why dust and gas escape easily from their surfaces.
