M class Stars not planets

> Hiya,

Or even "Wendy, Oh Be A Fine Girl Kiss Me Right Now Sweetie."

W are the rare Wolf-Rayet class, twice as hot as O's.
R,N,S are various forms of Red Giants, not so much stars as thin clouds of hot
to lukewarm gas.

B0 27 000 K blue-white
B5 16 000 K A0 10 000 K white A5 8 200 K
F0 7 200 K yellow-white

K5 4 300 K M0 3 700 K red M5 3 000 K

(These temperatures are in Kelvins. To convert from Kelvins (K) to degrees
Celsius (°C), just subtract 273.)

The Stellar database http://www.stellar-database.com/
has some good info, including "comfort zones", or how far away a planet should
be in AU (Astronomical Units) to be Earthlike. Earth is 1 AU away from Sol.

If you want random systems, have a look at

Finally, and this bit has nothing to do with the subject, a hilarious site I
found while doing a little research on the above:
