Planet Mercury and Planet Earth are both rocky planets. But Mercury is much smaller than Earth, so has much less force of gravity. Your answer is "No".
Pluto has a weaker gravity than Earth. In fact, Pluto has a weaker gravity than Earth's moon.
it has weaker gravity than Earth
Venus has weaker gravity than Earth.
Yes, it has weaker gravity than the sun.
weaker
It has much weaker gravity.
Weaker as it is smaller.
The "surface gravity" is slightly less than on Earth.
There less gravity on Mercury than on Earth.
Mars has a much weaker gravity than Earth.
