Planet Size Visualizer

Enter a radius in Earths or kilometers in the input box below. This will be the radius of the red circle. Earth is represented by the blue circle.

The circle on the left will shrink as the radius number is larger or smaller than 1.

Radius >=1 Earths: The circle on the right is your planet, the circle on the left is Earth.
Radius < 1 Earths: The circle on the left is your planet, the circle on the right is Earth.

At radius = 20 Earths or 1/20 Earths, the left circle will stop shrinking so it stays visible on the screen. The right circle will grow instead to reflect the red planet's radius.

Death Star I and II	Starkiller Base
The First Death Star has a diameter of 120 km. The estimates for the diameter of the Second Death Star range from 160 to 900 km. (Source)	Starkiller Base (the planet Ilum) is 4 times the size of the Death Star II. The diameter used for this program assumes the Death Star II is 900 km in diameter and Starkiller Base is 4200 km in diameter. (Source)
