What else can I help you with?
How do orbiters counteract the massive pull of a large planets gravity p?
centripetal acceleration counters the acceleration due to gravity creating an equilibrium. the EXACT same way water wont fall out of the bucket if you spin it fast enough. Gravity is also a field and decays as the distance between the two objects increases. GMm/r^2
Why does earth have gravity and the other planets do not?
All massive objects (including all planets) have gravity.
Are dwarf planets round?
Yes. While not considered planets, dwarf planets are still massive enough to be rounded by their gravity.
Which of the 4 terrestrial planets has the most gravity?
Earth is the largest and most massive of the four inner or terrestrial planets. Its surface gravity is therefore the highest of the four.
Does regular planets have weak gravity?
Generally speaking, the bigger or more massive a planet it, the more gravity it has, since gravity and mass are related. the small planets such as Mars and Mercury have a weaker gravity, while the larger planets have a strong gravitational field.
When is gravity at the largest?
Gravity is related to Mass and distance. Thus gravity increases the nearer you get to a dense massive body.
Why do all the planets have different fields of gravity?
Planets have different fields of gravity because their mass and size vary. The larger and more massive a planet is, the stronger its gravitational pull will be. The strength of gravity on a planet is determined by its mass and radius.
Do less massive planets have less gravitational force?
Gravity is the pull from matter. Less matter means less gravity, so yes.
What planet has the highest surface gravity of all the terrestrial planets?
Earth is the most massive terrestrial planet, so it has the highest surface gravity.
Are gassy planets really planets?
Yes! As long as it is massive enough to form a spherical shape with it's own gravity, and not so massive that it becomes a star, and revolves around a star itself, it is considered a planet.
What helps keep the planets orbiting the sun?
The planets orbit the sun due to gravitational attraction. The sun's massive gravity pulls the planets towards it, while the planets' tangential velocity allows them to move in a circular or elliptical orbit around the sun. It's essentially a balance between the inward force of gravity and the outward force of the planets' momentum.
Is the sun small or massive?
The sun is MASSIVE compared to all of the planets. The sun is SO HUGE, that if only it had gravity, it could pull every single planet in our solar system to a fiery death. ------------------------------------------ Correction: The gravity of the sun is the only thing keeping the planets in orbit. The sun is massive indeed compared to the Earth, but it is only an intermediate-sized star.
