how did the earth came into existance?

Answer 1

Via condensation and cooling of a planetary nebula. As this nebula contracted upon itself its fixed angular momentum meant that it had to rotate faster and faster( like a speedskater bring their arms in). The gases at the center of this rotating mass then reached such a high density that(theoretically) fusion occured and then and there our sun was born. The remaining fragments at various orbital distances became the planets we see today.
So theoretically, this is how all stellar systems come into existence- giants clouds of gas and dust contracting and then spinning and then fusing to form the sun and the planets.

Answer 2

Planet Earth is the third planet from the sun. The smallest distance to the sun is 147.100.000 km. The mean distance is 149.597.870 km and the biggest is 152.100.000 km. This is a result of the ellipsoid orbit of the planet (as is the case for all other orbits in the solar system).Earth travels around the sun in a year of 365,2418 days to be precise. It spins around in one day of 23 hours and 56 minutes.(23,933 hr).

Ever seen a beautiful planet????


The distance of the earth to the sun of 150 million km is important. It is the reason that it is not to cold and not to hot to support life. On Mercury for instance thrice as close to the sun it is far to hot; 400 degrees Celsius. On Pluto, almost forty times further away in space it is far to cold; minus 230 degrees Celsius. The moderate conditions make it possible that liquid water is flowing on our planet This could well be the main factor in our existence
Earth cam into being just like all the other planets. Big clouds of dust and gas surrounding the young sun coagulated and shrunk into bigger structures, the "planetesimalen" of tens to hundreds of km across. These lumps collided as a result of the gravitational pull and in the end it resulted in the nine planets we see today.

Answer 3

When the universe was much smaller, the law of gravity ensured that pieces of matter kept bumping into each other. Most of them became stars, but a significant number of the smaller bits became asteroids as the laws of motion tended to pull proto-asteroidal matter into elliptical orbits around proto-stars. Asteroids tended to aggregate into larger asteroids ie planets, though some of them never made it and are still asteroids.

One of those planets settled into orbit round one of those stars and became Earth... about 5 billion years ago.
