What is a frozen ball of dust?
comet
How long does it take for a star to be born?
Stars are created in stellar nebulae, which are enormous clouds of dust and gas in space (usually mostly hydrogen, as this is the most common element in the universe [90%]). The density of this dust is uneven, so gravity begins to draw it together around the points of higher density. As the dust gathers closer together, it draws in more dust due to its increased gravitational effects. This accumulation continues to grow, and as more and more dust packs on, the pressure in the center increases because all of the dust is pushing against it. Eventually, if there is enough matter, the pressure in the center will become so great that it pushes the hydrogen atoms together, causing nuclear fusion and creating helium. This fusion produces energy, which is released in the form of light and heat. This heat as well as the increasing mass causes more and more fusion, which snowballs until the whole gas ball is alight. This gas ball is now called a star, because it is emitting light and heat produced by nuclear fusion at its core.
How does gravity pulls gas and dust?
Gravity pulls gas and dust by exerting a force that attracts particles towards each other. The larger the mass of an object, the stronger its gravitational pull. As a result, gas and dust particles are pulled towards regions of higher mass, causing them to clump together and form structures like stars and planets.
What object does the force of gravity pull together?
dust
Where do stars begin their lives?
A star begins its life in cool clouds of dust and gas called a nebula.
What force caused a ball of dust rock and ice to be pulled together to form earth?
Gravity pulled together the tiny bits of matter that eventually formed the Earth.
Do dwarf stars begin their life as planets?
No, but planets or planet dust could be pulled together to make a star, resulting in a dwarf star. (in theory)
A large ball of ice and dust?
my sister is a dust ball of ice thats the shittest answer ever
Can you eat a dust ball?
Yes, but it is ill-advised. (You don't want to know what all is in a dust ball.)
What is is solar nebula?
A solar nebula is a place where new stars are formed. Stars are "born" here when giant dust and gas clouds are pulled together under the force of gravity.
A star begins as a?
As a nebula, a cloud of gas and dust.
What is a frozen ball of dust?
comet
What made the solar system and planets?
This is what scientists think happen: a previous large star exploded in a supernova. The outer layer of dust and gas is ejected into space. The gas eventually formed the sun. The dust pulled together to form everything else in the solar system.
Is the moon a massive ball of dust and heat?
No
Can earth become a dust ball?
Definately not!
Where did Uranus get its rings?
they came from a cloud of gas and dust that got pulled in its atmosphere.
How and why do comets change their appearance as they come closer to the sun?
Comet are made of rock and ice. The tails are made of dust. Therefor as it approaches the sun the ice begins to sublimate and the dust begins to disperse.
