The gravity on other planets is NOT directly affected by the distance of that planet to the sun. The mass and the dimension of that planet is what defines the force of gravity.

Gravity from the sun is strong enough to keep all the planets ornitting the sun, the gravity from earth
effects the moon, I think Jupiter has several moons, one of which is called Europa, and the gravitational attraction from Jupiter keeps all of its several moons orbiting. The mass of a planet affectes its gravity. But other than keeping it in the same orbit the sun has no effect on the gravity fo other planets.

Do you mean the gravitation attraction BETWEEN the Sun and planets? In that case, given fixed masses for both objects, the gravitational attraction is the inverse square of their distance. In other words, if you double the distance between the two objects then the gravitational attraction is 1/4 of what it was (1/2^2). If you triple the distance the attraction is 1/9 (1/3^2) of what it was.

It's not affected by the sun, it's affected by the planet's mass. That is why Jupiter's gravity is stronger than Earth's even though Earth is closer to the sun.

This is how other planets in other solar systems were found. The planets gravity gently tugs the star as they orbit around it.
You can tell by the way the star"wobbles" by the dopplar shift.

Gravity is caused by mass - doesn't have much to do with the sun.

Those things are fakes. You cannot have a star named after you. Stars names are a competence of the International Astronomical Union.
