It is.
Every FAQ or introduction text to general relativity should explain that.

Yes, gravity does affect time on different celestial objects. This is known as gravitational time dilation, which is a phenomenon predicted by Einstein's theory of general relativity. Essentially, the stronger the gravitational force, the slower time moves. This can be observed in experiments such as the famous Hafele-Keating experiment, where atomic clocks placed on airplanes showed a difference in time compared to stationary clocks on the ground due to the difference in gravitational forces.

On different celestial objects, the strength of gravity can vary greatly. For example, on a massive object like a black hole, the gravitational force is so strong that time essentially stops at the event horizon. On the other hand, on smaller objects like asteroids, the gravitational force is much weaker and therefore the effect on time is minimal.

In summary, yes, gravity does affect time on different celestial objects due to the varying strength of gravitational forces. This is a fascinating aspect of the universe that continues to be studied and understood by scientists.
