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 is a plantary nebual?
A nebula where planets are created along with stars.
Why do planets need their stars?
Planets do not technically need their respective stars, but stars keep planets in orbit and provide heat and light to the planets.
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.
What is a scientist who studies stars and planets?
An Astronomer is a scientist who studies the stars and 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".
How was the galexy created?
it was created by many stars and planets,and space
What is a plantary nebual?
A nebula where planets are created along with stars.
Do stars orbit planets or planets orbit stars?
Planets orbit stars.
Who did space start?
It started with the big bang. This created the stars and planets
What is hotter planets or stars?
stars, the planets have to get heat from stars
Why do planets need their stars?
Planets do not technically need their respective stars, but stars keep planets in orbit and provide heat and light to the planets.
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.
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.
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.
Which galaxy are the planets on?
Planets orbit stars, stars orbit a galaxy. Planets are not "on" anything. A lot of stars out there have planets - we are just finding out how many now that we have better techniques to find them. So probably all galaxies have at least some stars with planets.
What is a scientist who studies stars and planets?
An Astronomer is a scientist who studies the stars and planets.
