Planet Rotation Period

These calculators calculate the rotational period of a planet given its mass and density. Select a calculator below.

Terrestrial Planers (Mass ≤ 10 Earths) Jovian Planets (Mass > 10 Earths)

Date Info
8/1/20 - 10/8/20

8/1/20 - 10/8/20: Developed and completed first version of the program. It can be viewed here.

This earlier version of the program was able to:

  • Calcualte the rotational velocity of a planet given its mass and density.
  • Calculate the gravity of a planet given its mass and density.

However, the program was unable to calculate the mass of a planet given its density and rotational velocity. This feature was added to the second version of the program.
5/24/21 - 6/4/21 Programed algorithm in Google Colab using Python that calculates mass from rotation velocity and radius from the given formula.
6/23/21 Added algorithm to Planet Rotation calculator. Used code so the program code will operate on the Terran and Jovian pages, without having to copy-paste all the code to the other page. Rather, the same code is used for both pages by using a div element and Javascript code to import an html file containing the calculator code to the page.
