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.

The effect is very small.
Yes, gravity affects your weight on different planets. Weight is a measure of the gravitational force acting on an object, so on planets with stronger gravity, you would weigh more, and on planets with weaker gravity, you would weigh less compared to your weight on Earth.
You know that no planets actually orbit the earth right? ...?
earths rotation around the sun
"Gravity" is responsible for the existence of planetary orbits, and for their shapes and periods. It's also the reason for the spherical shapes of the planets, and for the existence of atmospheres, in the case of those planets that have any.
Gravity keeps the planets in orbit around the sun and the stars and the stars in orbit around the center of the galaxy. Gravity also holds the stars together against their own internal pressure.
Yes, planets and the sun interact through gravitational forces. The sun's gravity keeps the planets in orbit around it, while the planets' gravity tugs on the sun, causing it to wobble slightly. Additionally, the sun's energy and solar wind affect the planets' atmospheres and magnetic fields.
Planets have gravity because they have mass.
the sun holds 98% of the solar system.
The other planets do have gravity.
Our planets are kept in their orbits around our star by the force of gravity.With all due respect, I should be surprised if the principle were not the samewhere you come from.
