How were planets made?

Question

I'm very curious.

Answer 1

Ever seen dust bunnies in your house? Where do ya think they come from? Answer: from dust. The dust particles are in the air and have an electrical charge. As they swirl around in the air they eventually bump into each other and stick together just like a balloon will stick to your sweater if you rub it and give it an electrical charge. When enough of the dust particle have stuck together their combined weight is heavier than air and they settle to the floor. More dust particles floating around bump into these collections and eventually there is enough of them to form a kind of web that looks kind of like a hairball - this is what you call a dust bunny. Planets form in a very similar way. Cosmic dust floating around in space starts to come together due to gravitational forces and co-agulates into a ball which now has more gravitational strength. As it floats thru space it accumulates more dust particles and this goes on and on until there is a planet. Cool huh?

Answer 2

It is not known with certainty how planets are formed. The prevailing theory is that they are formed from those remnants of a nebula that do not condense under gravity to form a protostar. Instead, these remnants become a thin, protoplanetary disk of dust and gas revolving around the protostar and begin to condense about local concentrations of mass within the disc known as planetesimals. These concentrations become ever more dense until they collapse inward under gravity to form protoplanets.[9] After a planet reaches a diameter larger than the Earth's moon, it begins to accumulate an extended atmosphere. This serves to increase the capture rate of the planetesimals by a factor of ten. [10]

When the protostar has grown such that it ignites to form a star, its solar wind blows away most of the disc's remaining material. Thereafter there still may be many protoplanets orbiting the star or each other, but over time many will collide, either to form a single larger planet or release material for other larger protoplanets or planets to absorb.[11][12] Those objects that have become massive enough will capture most matter in their orbital neighbourhoods to become planets. Meanwhile, protoplanets that have avoided collisions may become natural satellites of planets through a process of gravitational capture, or remain in belts of other objects to become either dwarf planets or small solar system bodies.

The energetic impacts of the smaller planetesimals will heat up the growing planet, causing it to at least partially melt. The interior of the planet begins to differentiate by mass, developing a denser core. Smaller terrestrial planets lose most of their atmospheres because of this accretion, but the lost gases can be replaced by outgassing from the mantle and from the subsequent impact of comets.[13] (Smaller planets will lose any atmosphere they gain through various escape mechanisms.)

With the discovery and observation of planetary systems around stars other than our own, it is becoming possible to elaborate, revise or even replace this account. The level of metallicity is now believed to determine the likelihood that a star will have planets.[14] Hence it is thought less likely that a metal-poor, population II star will possess a more substantial planetary system than a metal-rich population I star.

Answer 3

There is more than one proposal on how planets are made. The general idea is that when you have a bunch of stuff (matter) such as that in a nebula, it will generally collapse, either by gravity, (the more "stuff" you have, the greater it will act on other "stuff") or by shockwaves such as that of a nearby exploding star. Matter will then be pulled towards a center by gravity. As more and more matter get's pulled to the center, particles will collide and produce nuclear reactioons and produce heat, forming an early star. While the material in the center becomes hotter because of the fusion of these particles, the material further away begins to cool and condense into very tiny grains of matter. Any matter that does not condese begins to be swept further and further away due to the solar winds created from the newborn star. This is why planets closest to the sun are made up of heavier materials such as iron, and outer planets are made up of gases. As the first bits of matter began to condence, they continue to collide and stick together, forming larger and larger pieces called planetesimals. These planetesimals continued to grow by "sweeping" out all the materials in their path. Planets closest to the star will warm which will cause the lighter elements like hydrogen and ammonia, to rise and form an early atmosphere, which is mostly carried away by solar winds. Planets farther away from the star will stay cool enough that the condesed gas remains.

Answer 4

Condensation and collisions from the pre-solar system gases. The current theory is our solar system is the remnants of a prior super nova, hence the heavy metals that exist on our planet. When the gases condensed while spinning due to graviational forces, many of our planets were formed.

Answer 5

I thought about this same thing before and researched on it so check my source. I guess they are still researching about that as the article is recent one.

Answer 6

God created the sun, and the earth. Dust particles and other celestial bodies (asteroids, ect.) fuse to produce planets.
