Extrasolar Planets

[WarK]

Manually. You can open any .ssc and .stc file and see that definitions for stars and planets are pretty straightforward. It doesn't take much effort to write one up and craft planets and stars all over the Universe.

Gods have been doing this for millennia

Damn, I think I've just discovered a god

~50 New planets. 16 are super-Earths.

Looks like the planets at 82 Eri and HD 85512 are reported here as well.

Kepler-16b, the first transiting circumbinary planet.

G+ is flooded with comments about finding Tatooine, lol.

It should be noted that Kepler-16 b is not the first circumbinary planet found. PSR B1620-26 b holds that title. Eclipsing binaries found to host planets since then include DP Leonis, HW Virginis (two planet candidates), NN Serpens (two planet candidates), HU Aquarii (two planet candidates), and UZ Fornacis (two planet candidates).

Kepler-16 b is unique only in that it is the first to transit a binary pair, and that its host stars are both on the main sequence.

Image of a planet at FU Tau. It's been known about for a little while now, but IIRC, it has just recently been confirmed to be bound to the system.

Wow, the data in the link is quite interesting. 800AU away from the parent star? I'm surprised they noticed it at all; I thought almost all the planets so far discovered are very close to their parent so they cause the star to wobble noticeably over days or weeks.

What does it mean by a mass of 15 MJ? I take it M stands for Mass rather than Mega, or that would be absurd.

I believe it stands for "Mass of Jupiter".

This planet was detected using a different method (direct imagery), rather than the wobble method. Using the wobble method would probably take millennia for this planet.

Correct.

Three planets (two Neptunes in a mean motion resonance and a super-Earth further in) transiting Kepler-18.

Recovery of the outer three planets at HR 8799 with old (1998) HST data, providing a much improved observational baseline with which to calculate their orbits.
Press release.

Aside from a scattering of planets that today don't really make the news, it's been pretty uneventful until now. However a second planet has been found in the Gliese 667 C system. The planet is about four times the mass of Earth and receives 90% of the insolation from its star that Earth receives from the sun. This planet would therefore seem to be a candidate for habitability.
