Stars came first. These coalesced from clouds of primordial hydrogen. Primordial means primeval, or existing from the beginning. There were no stars, just a hot expanding cloud of gas.
The gas formed knots and clumps, and these coalesced into protostars. A protostar is a star that emits light via gravitational collapse alone. Infalling matter, sucked in by the star's accumulating mass, would heat up by friction and pressure. Eventually the core of each of these protostars became hot enough for the hydrogen to fuse to helium. In bigger stars, helium fusion would eventually give way to fusion of heavier and heavier elements, ending with iron.
The biggest stars would collapse, and the collapse would result in a tremendous burst of energy flinging all these elements back out into space, while slamming atomic nuclei together to synthesize heavier elements, ranging from iron to uranium.
The collapse of circumstellar disks of such debris would result in stars orbited by "rocky" planets like Mercury, Venus, Earth, and Mars, gas giants (hydrogen and helium not pulled into the star), rings of more distant icy objects like the Kuiper Belt, and shells of more distant objects yet like the Oort Cloud.
What else can I help you with?
Do planets and moons have stars?
On the contrary! A star has planets, which circulate it. And planets have moons. Stars do not circle planets.
Do the stars orbit the planets or do planets orbit stars?
Moons orbit planets. Planets orbit stars. Some stars orbit other stars, or orbit their mutual center of gravity. Stars orbit the center of the galaxy. Galaxies may orbit the center of the "galactic group".
What is a scientist who studies stars and planets?
An Astronomer is a scientist who studies the stars and planets.
What are two ways that planets are different from stars?
1) Although planets can be composed primarily of rock or gas, only stars are objects made of gas that are massive enough to support a nuclear fusion reaction. 2) Although planets and stars can orbit stars (as in binary systems), stars never orbit planets.
Why do planets need their stars?
Planets need their stars for heat and light, which are essential for supporting life and maintaining stable surface temperatures. Additionally, the gravitational pull of the star helps to keep planets in orbit around it.
How was the galexy created?
it was created by many stars and planets,and space
Do stars orbit planets or planets orbit stars?
Planets orbit stars.
Do planets and moons have stars?
On the contrary! A star has planets, which circulate it. And planets have moons. Stars do not circle planets.
Who did space start?
It started with the big bang. This created the stars and planets
Which pulling force do planets and stars have?
Planets and stars have gravity.
What makes stars and planets?
The Solar System Makes the planets and the Stars.
Do the stars orbit the planets or do planets orbit stars?
Moons orbit planets. Planets orbit stars. Some stars orbit other stars, or orbit their mutual center of gravity. Stars orbit the center of the galaxy. Galaxies may orbit the center of the "galactic group".
What is jathakam?
It's a script/document containing ones planetary positions/information to understand, forecast, predict ones future health, wealth, illness, prosperity in alignment with planets/stars. The reason it's in alignment with planets/stars since the galaxies created planets/stars and also the life on earth hence we are stars ourselves.
Is stars planets?
No. Stars are like suns, around which planets may orbit.
Who studies stars and planets?
Astronomers (and their ilk) study stars and planets.
Can planets and stars orbit around the sun?
Planets orbit the sun. Stars do not.
What is a scientist who studies stars and planets?
An Astronomer is a scientist who studies the stars and planets.
