the gravitational forces from nearby solar systems allowed a nebula to form and in that nebula were all the compounds needed to form the sun and planets.
Gravity.
The Moon is a satelite of the Earth and the Earth is the 3rd planet out form the Sun in the solar system.
Together with the central star, they form a solar system.
The sun was likely created about 5 billion years ago along with the Earth and later the moon. Because it is not a SOLAR system without a sun, this means that the solar system itself was created around this time
Not in our own solar system. The orbits of all the planets in the solar system have stabilized, and there isn't enough mass in the remaining asteroids to form a new planet. Else where, however, there are solar systems that are still forming, with new planets that are yet to form.
We strongly suspect that every other solar system will be different, probably RADICALLY different, from our own. Every star is a little different; the mass that coalesced to form the solar system is different, and the unimaginably random factors that caused each solar system to form as it did - those are also different.
The Solar System is a oval because that how the planets form it .
There is only one star in our solar system and that is the sun.
Venus is the second planet out form the Sun in the solar system.
Gravity.
No. They form in the outer solar system where it is cold enough.
The solar system is estimated to be approximately 5 billion years old.
Asteroids, comets, planets, the Sun and other object form the solar system
A solar system!
The Moon is a satelite of the Earth and the Earth is the 3rd planet out form the Sun in the solar system.
Almost everything in the solar system at this time. Planets, Moons.
Together with the central star, they form a solar system.
