Planet Janssen

I wanted to give a shout out to my dear friend Jantzen! She was very excited to learn that scientists have discovered a planet that has her same name! Well, almost. The name of the planet is Janssen.

Janssen orbits two stars known as 55 Cancri A and 55 Cancri B. 55 Cancri A is a G8V Yellow Dwarf Star and 55 Canri B is an M3.5V Red SubDwarf Star. The 55 Cancri Star System is 40.2470 light years away from Earth. A light year is equal to 5.879 trillion miles! Therefore, the planet Janssen is 236.612113 trillion miles from Earth!

The planet Janssen is a scorching hot SubNeptunian Planet. It has an average temperature of 1,588 degrees Fahrenheit! By comparison, Earth has an average temperature of 57 degrees Fahrenheit, and hot Venus is “only” 847 degrees Fahrenheit, half as hot as Janssen.
