How was our planets born?

Question

How was our planets born?

Answer 1

Our solar system started forming nearly 4.6 billion years ago form a protoplanetary disk! A disk of gas and dust that rotates around a star(our Sun). The fragments of rock in this disk kept colliding and merging and as they got bigger they started to attract more and more solid matter until eventually cooling down and becoming rocky planets like Mercury, Venus, Earth and Mars. The gas giant planets (Jupiter, Saturn, Uranus, and Neptune) formed further out, beyond the frost line, the point between the orbits of Mars and Jupiter where the material is cool enough for volatile icy compounds to remain solid. The ices which formed the Jovian planets were more abundant than the metals and silicates which formed the terrestrial planets, allowing the Jovian planets to grow massive enough to capture hydrogen and helium, the lightest and most abundant elements. Planetesimals beyond the frost line accumulated up to four Earth masses within about 3 million years. Today, the four gas giants comprise just under 99% of all the mass orbiting the Sun. Theorists believe it is no accident that Jupiter lies just beyond the frost line. Because the frost line accumulated large amounts of water via evaporation from infalling icy material, it created a region of lower pressure that increased the speed of orbiting dust particles and halted their motion toward the Sun. In effect, the frost line acted as a barrier that caused material to accumulate rapidly at ~5 AU from the Sun. This excess material coalesced into a large embryo of about 10 Earth masses, which then began to grow rapidly by swallowing hydrogen from the surrounding disc, reaching 150 Earth masses in only another 1000 years and finally topping out at 318 Earth masses. Saturn may owe its substantially lower mass simply to having formed a few million years after Jupiter, when there was less gas available to consume.

Answer 2

Read the Quran/ Suraa-Enbiya 30.

Which: " Do not the Unbelievers see that the heavens and the earth were joined together (as one unit of creation), before we clove them asunder? We made from water every living thing. Will they not then believe?"

Answer 3

After the birth of our Sun, a flattened disc of solid dust particles revolved round it due 2 its gravity. These particles in the flat disc collided into each other and started becoming huge masses.These masses came 2 b known as planets. There were more than 20 planets at that time with irregular orbits. Due 2 these irregular orbits, many collisions took place one of which created our moon too. These collisions broke planets into planetoids and even created huge masses. When particles decreased after this round of collision, the planets were finally created with organised and principled orbits. The remains were small planetoids known as asteroids which got their place in the Main belt or the Asteroid Belt between the orbits of Mars and Jupiter. Some of  the other small icy and dusty snowballs known as Comets settled in the Edgeworth- Kuiper belt beyond the orbit of Neptune. The others were settled in the Oort Cloud that lies in the planetary part of the Solar System. Some Asteroids or planetoids were attracted by the gravity of the planets and became their satellites.

Thus, the planets were formed.

Answer 4

Scientists have been able to reconstruct detailed information about the planet's past. Earth and the other planets in the Solar System formed 4.54 billion years ago out of the solar nebula, a disk-shaped mass of dust and gas left over from the formation of the Sun. Initially molten, the outer layer of the planet Earth cooled to form a solid crust when water began accumulating in the atmosphere. The Moon formed soon afterwards, possibly as the result of a Mars-sized object (sometimes called Theia) with about 10% of the Earth's mass impacting the Earth in a glancing blow. Some of this object's mass would have merged with the Earth and a portion would have been ejected into space, but enough material would have been sent into orbit to form the Moon.

Outgassing and volcanic activity produced the primordial atmosphere. Condensing water vapor, augmented by ice and liquid water delivered by asteroids and the larger proto-planets, comets, and trans-Neptunian objects produced the oceans. The highly energetic chemistry is believed to have produced a self-replicating molecule around 4 billion years ago, and half a billion years later, the last common ancestor of all life existed.

Answer 5

I read Genesis and laughed at its pure stupidity. The planets were not formed as a result of God, or during the big bang. They were formed because of left over matter from the sun's formation. Some of this matter condensed, making very massive objects. A majority only turned out to be asteroids but some became planets, and others became moons. There is still some cosmic dust left from the solar system's formation but most of it has condensed.

Answer 6

Our planets were formed by a explosion called big bang, It exploded some kind of these things that became formed into planets and stars and galaxys!

Answer 7

Big-bang!!!!

Read the Quran/ Suraa-Enbiya 30.
