A planet (or comet) will speed up as it approaches the sun.

There are many factors that can affect the speed of a celestial body as it moves towards or away from the sun.

The gravitational pull on an object will change depending on how close it is to the sun, and this affects its speed.

It also depends on what type of object we are talking about.

For example, a planet will speed up as it approaches while a comet will slow down.

Finally, there is the solar wind which has an effect on all objects in space near our star!

The gravitational pull on an object will change depending on how close it is to the sun, and this affects its speed.

Bullet Point: Once you approach the sun’s surface (or approximately 150 million kilometres from the Sun) .

The pressure becomes so great that electrons break free from atoms in your spacecraft or other planetary body.

This creates plasma around your craft or body with temperatures reaching millions of degrees Celsius – hot enough to melt lead if you were any closer than 150.
