How are planets formed step by step?
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.
What are the 4 stages of Earth’s formation in order?
After becoming distinct planets, they went through four stages of formation: Differentiation, Cratering, Flooding and Surface Evolution. For Earth, these changes led to the planet we know today, layered with an iron core, a weathered, shifting surface, water and life.

How are planets built?
Planets form from particles in a disk of gas and dust, colliding and sticking together as they orbit the star. The planets nearest to the star tend to be rockier because the star’s wind blows away their gases and because they are made of heavier materials attracted by the star’s gravity.
What are the 2 main types of planets?
Planets are generally divided into two groups: the terrestrial and the giant planets.
Can a star turn into a planet?
Yes, a star can turn into a planet, but this transformation only happens for a very particular type of star known as a brown dwarf. Despite beginning life as a star, a brown dwarf quickly uses up its heavy hydrogen, goes dark, cools, and spends the rest of its life as a planet.
Is a sun a planet?
Of the objects that orbit the Sun directly, the largest are the eight planets, with the remainder being smaller objects, the dwarf planets and small Solar System bodies….Solar System.

What does Venus look like?
Venus is the brightest object in the sky after the Sun and the Moon, and sometimes looks like a bright star in the morning or evening sky. The planet is a little smaller than Earth, and is similar to Earth inside. We can’t see the surface of Venus from Earth, because it is covered with thick clouds.
