Why is 55 Cancri e not habitable?
As was noted on The Space Reporter, being rocky and having an atmosphere does not make 55 Cancri e habitable for life, as the planet is too hot to have liquid water on its surface.
How does 55 Cancri e compare to Earth?
55 Cancri e is a super-Earth — about twice our planet’s size — that zooms around its star in 18 days. It has a surface temperature of nearly 4,900 degrees Fahrenheit (2,700 degrees Celsius). For a while it was dubbed the “diamond planet” because scientists suggested that it was composed of diamonds and graphite.
What type of planet is 55 Cancri e?
super-Earth exoplanet
55 Cancri e is a super-Earth exoplanet that orbits a G-type star similar to our Sun. Its mass is 8.08 Earths, it takes 0.7 days to complete one orbit of its star, and is 0.01544 AU from its star. Its discovery was announced in 2004.
What type of star is 55 Cancri A?
yellow dwarf star
55 Cancri A is a yellow dwarf star of spectral type G8V. It has a similar mass to our Sun, but is cooler and less luminous. The star is more enriched than our sun in elements heavier than helium: it is classified as a rare “super metal-rich” main sequence star and has around 186% the solar abundance of iron.
