Lightest Exoplanet Is Discovered... only 1.9 Earth Masses...

Post by Col Man »

If anyones interested in exoplanets like i am then i saw this article today on the bbc website. : http://newsvote.bbc.co.uk/1/hi/sci/tech/8008683.stm

i was shocked actually that they brought out the news before i saw it on the exoplanet websites :shock:

if you dont know about them :

http://exoplanet.eu/index.php
http://planetquest.jpl.nasa.gov

its too close to its star for life (orbits closer than mercury would in our solar system) and its the fifth planet found for that system (Gliese 581)

its another step along the road to finding another planet like earth.. not long now ;)

Thanks for the link. I caught the tail end of a radio news report and just heard that a planet not much larger than Earth had been discovered and another with the possibility of oceans (don't think they mentioned they were in the Gliese system). I will be keeping an eye out for findings by Kepler as I find this a fascinating field in astronomy.

All the best

I wonder what happened to exoplanet CoRoT-Exo-7b, which orbits a 12th mag star in Monoceros, is 1.7 Earth masses and was the feature article in the latest S&T magazine?

That was a good point joe and i remembered something like that too, so ive been checking on the net and at the corot esa website it doesnt give a mass it just says its less than ''twice the size'' of earth

http://www.esa.int/esaSC/SEM7G6XPXPF_index_0.html

but on wikipedia it states that corot-7-b is 1.7 times the diameter of earth and 5.6 to 11 earth masses

link here so you can check : http://en.wikipedia.org/wiki/COROT-Exo-7b

i checked to in the exoplanet encyclopedia and it states the same as in wikipedia.

maybe S&T made an error and said mass instead of diameter.

hope this sorts out the confusion :)

More likely me confusing my Earth diameters with my Earth masses.
