Scientists think planets, including the ones in our solar system, likely start off as grains of dust smaller than the width of a human hair. They emerge from the giant, donut-shaped disk of gas and dust that circles young stars. Gravity and other forces cause material within the disk to collide.
How are planets formed step by step?
According to our current knowledge, planets are formed around a new star by condensing in a disc of molecular gas and dust, embedded within a larger molecular cloud. Condensation increases until they become giant planets, which are heated, then cleanse their orbits in the disc and possibly bend it.
How are planets born?
Planets are born from the clouds of gas and dust that orbit new stars. Billions of years ago, circumstances were just right for Earth and the other planets in our Solar System to form. The Solar System that we live in consists of a medium-size star (the Sun) with eight planets orbiting it.
Can a star turn into planet?
Yes, it is possible for stars to turn into planets. But this happens for only a specific category of stars- called as brown dwarfs.
Who created planets?
The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. The Sun formed in the center, and the planets formed in a thin disk orbiting around it.
Can we create a planet?
Whether it is constructing a planet-like space station or a full planetary replica, we are unlikely to witness this feat, at least in our lifetimes. However, terraforming an existing planet is a more viable option. These days, it seems like everyone wants to go into space. Some even want to build a nation in space!
Who made the planets?

Can a planet have 2 suns?
Can a planet really have two suns? While many things about Star Wars are purely fictional, it turns out that planets orbiting two or more stars is not one of them. In 2011, NASA embarked on the Kepler mission, exploring the Milky Way galaxy to find other habitable planets.
Can the sun burn out?
But in about 5 billion years, the sun will run out of hydrogen. Our star is currently in the most stable phase of its life cycle and has been since the formation of our solar system, about 4.5 billion years ago. Once all the hydrogen gets used up, the sun will grow out of this stable phase.
Why is Earth habitable?
What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.
