The planets' own gravity has made them spherical. Also there are other effects such as their ability to retain an atmosphere, etc. The Sun's gravitycauses the orbits of the planets.
No, because there is no such ting as a planet with zero gravity.
Neptune.
There is a force that unites the tides, planets and black holes. Tides are generally thought of as the rise and fall of the level of the oceans due to the gravitational effects of the moon and the sun. Planets have gravity proportional to their masses, and black holes are points of massive gravity. Gravity or its effects unite the three things listed.
Gravity, together with the planet's total kinetic and potential energy, completely determines the size and shape of the orbit.
The sun's gravity has a number of effects on the planets. Primarily, the sun's gravity is what sets the orbits of the 9 planets. With one revolution around the sun equaling a solar year (365.25 days on earth). Planets closer to the sun orbit the sun at higher speeds due the sun's gravity being stronger at short distances (Gravity decreases exponentially as distance increases from an object) The sun's gravity also has major tidal effects on the planets. High and low tides cycles on earth are partially a function of differences in the sun's gravity on different portions of the earth. The sun's gravity pulls slightly more on the side of the earth facing the sun, causing fluids to bulge toward that side resulting in a high tide cycle. On Mercury, where the sun's gravity is much stronger, tidal forces are powerful enough to alter solid rock and effect the planets landscape.
Planets have gravity because they have mass.
Gravity itself cannot be seen, as it is a force of attraction between objects with mass. However, its effects can be observed, such as objects falling to the ground or planets orbiting around the sun.
the planets orbit the sun right.so that means that the earth a part to so if gravity ,then what would earth land on if there was gravity
The other planets do have gravity.
There are two dominant effects of the Sun on the planets in the Solar System. It binds them into their orbits gravitationally, and it warms them with its radiation. It also provides light, presumably mainly of interest to us here on Earth, and the Solar Wind of particles from the Sun bombards our atmosphere continually sometimes causing electrical effects in satellites and on the ground.
