Formation of Our Solar System Timeline
1. Look at the six statements below and put the events in order from beginning to
end.
2. Place the numbers 1 through 6 on the lines provided, 1 will be the beginning and
6 will be the end.
Somewhere in the Milky Way galaxy, a star went supernova. The explosion
transferred energy to a cloud of gas and dust that was nearby.
As the energy began to disturb the cloud of gas and dust, gravity caused the
cloud to collapse in on itself and form a disc.
The center of the disc became hot enough and under enough pressure to form a
star: the Sun.
The force of gravity began pulling the remaining gas and bits of dust together to
form planets and moons.
Near the Sun, the rocky planets of Mercury, Venus, Earth, and Mars formed.
In the outer cooler regions of the disc, the ice and gas planets of Jupiter, Saturn.
Uranus, and Neptune formed.

Explanation:

The question above refers to the origin of the solar system.

This system was created from a supernova, which generated an extensive cloud of dust and gas that was constantly rotating within itself. This gas cloud received great energy from the explosion to create the super nova. This energy added to the weight of the cloud itself, caused the cloud to flatten and take the form of a disk. The center of that disk was under such great pressure and temperature that it reacted and formed the sun.

Around the center of the disk, there were several pieces of solid material, which have been clumping with time over bodies, these bodies formed the moons and the planet.

As you may already know, the hottest planets are those that are closest to the sun and that have rocky composition, they are: Mercury, Venus, Earth and Mars.

On the other hand, the most distant clusters of the sun formed planets of gaseous composition which are: Jupiter, Saturn, Uranus and Neptune.
