Asteroids and Meteorites
The sun formed first. The moon was not formed until around after the formation of proto-Earth.
they formed around the same tome
A planet is formed out of hot gases revolving around the Sun.
The first stars appeared about 400 million years after the big bang. Galaxies would have formed around 2 billion years later.Our Sun was formed about 9.2 billion years after the big bang.
The first planet formed in our solar system is believed to be Mercury. It originated from the leftover gases and dust surrounding the young Sun about 4.5 billion years ago.
The Sun formed first, so it is the youngest compared to the planets.
We may not have enough information yet to answer this question, since we don't have substantial geological knowledge of all the planets. According to the current understanding, they were all being formed about the same time. The immense disk of materials that formed around the sun, the accretion disk (a little like the rings of Saturn) was condensing into planets more or less simultaneously.
Sun first, then the earth and moon formed at the same time around 4.65ga (billions of years ago) when a large moon-sized planet collided with the proto-earth/moon system.
Scientists estimate that the sun formed around 4 billion years ago.
They have their own orbits, around the star they formed around, just like how our planet orbits our sun.
A year is formed by the earth orbiting all the way around the sun.A year - is the time taken for the earth to travel once around the sun.
It was there first - the sun was always the center of the dust/gas cloud that formed the solar system.
