In theory, the gravity of each object in the universe affects every other object in the universe. If you do the math, you will see that the effects can be so small for one object that they vanish, for all intents and purposes, over huge distances. But the combined effect of gravity from every single bit of mass in the universe is another matter. Some theorize that inertia may be a result of this cumulative affect. Regarding the solar system, the sun is massive enough to keep all of the planets and countless other smaller bodies in orbit. The planets and other bodies are kept in place because their inertia, their tendency to go in a straight line, is balanced by their gravitational pull toward the sun. In a sense, everything in orbit is "falling" toward the sun, but "missing" it because the orbital velocity keeps them "wanting" to move in a straight line.
For starters, the sun is a huge globe or sphere of gases and few metals. It's roughly 100 thousand times bigger than earth meaning it has an insane mass. It's mass therefore makes it's gravity very large too. Because of the enormous amount of gravity it has, everything from a few inches away from it to further than the orbit of Pluto is trapped and (very) slowly moves toward it. However, it's not just the sun's gravity that holds the solar system. It's also it's inertia and other celestial bodies' gravity and inertia, too. Inertia is kind of like anti-gravity so it repels things which is why earth doesn't just fly directly into the sun. This combination of gravity and inertia is what causes our planets to orbit along with meteors and comets.
Without the gravitational pull between the planets, their moons, and the Sun, the Solar System would not exist at all.
Why is that? It's because the gravity of the Sun pulls all 8 planets into orbit, and if there was no gravity, all planets would go astray and get far away from the Sun.
gravity trapped planets in orbit of the sun.
the sun is really big and so pulls smaller objects around it and so the planets orbit the sun.
The mutual (2-way) forces of gravity between the sun and objects in
the solar system is what keeps the objects in orbit around the sun.
It is essential to the solar system because without gravity all the planets would travel off into space. Gravity is what holds the planets in their orbits.
Gravity keeps objects in orbit around the Sun; it keeps the objects together; and the gravity from one object can perturb the orbit of other objects.
The Sun's Gravity
Our solar system consists of the sun, the planets, their moons, and a variety of smaller objects. The sun is at the center of the solar system, with other orbiting around it. The force of gravity holds the solar system together.
the moon to orbit the earth
The different parts of the Solar System attract one another through gravity. Since the Sun has most of the mass of the Solar System, other objects are mainly attracted to the Sun.
A gamma ray burst would certainly affect earth, depending on how far away it is. It could come from outside the solar system.
Gravity is the force which keeps them there.
gravity
nothing, there is no gravity in space
Gravity!
easy gravity :)
The Sun's Gravity
Without gravity in our solar sytem and our universe everthing would float and it would affect our orbit in the solar system
Gravity causes objects, like planets, to orbit the Sun.
no. gravity acting on an object depends on the mass of each of the nearby objects. The solar system is not uniform in mass, so gravity is not uniform either.
They are all in orbit.
The gravity of all the planets and the alignment of them.
it is a force called gravity.
