All masses attract one another. Do some reading about the general law of gravitation for more information.
"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.
'Gravoty' is an attraction between any two or more objects, be those objects atoms, protons or planets. stars andything in between. The planets have gravity , the Sun has gravity. They are attracted to each other. So why do they not 'crash' into each other? Because, the planets are moving with an acceleration. This acceleration together with the planets mass creates are force (F = ma). This force is balanced by the Sun's force of gravity. So the forces are in balance, so the planets orbit the Sun and not fall into the Sun. The oceans on Earth, being liquid, will be attracted to the Moon by Lunar gravity. So which side of the Earth the Moon is on , will be the 'High Tide'. This is balabnced 'Like a wheel balance', by a counter High Tide on the opposite side of the Earth, from the Moon.
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.
Yes, all planets have gravity. Gravity is a force that attracts objects with mass towards each other, so every celestial body with mass, including planets, has its own gravitational pull.
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.
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 other planets do have gravity.
the sun holds 98% of the solar system.

The effect is very small.
All massive objects (including all planets) have gravity.
my inability to go to other planets. and gravity
All planets are affected by the gravity of other planets.
The planets have constant effects on human lives despite the inability to see the majority by human eye. The planets alter weather, gravity, daylight, and many other aspects.
because of the gravity of the other planets around them
Simple. Gravity! The planets are dragged in by the gravity of the sun.
