Talk:Epsilon Reticuli b

[edit] This is hilarious

I'll add insolation calculations and the comparison chart when I have more time, but this planet is no where near Earth in insolation...

[edit] Some non-original-research using known values and basic algebra:

I disagree that the figure for the Earth's Solar constant at Solar Constant are accurate,
I've read various different quotations of the value in texts and on the net. A little accuracy wouldn't hurt:
R= 6.955e8 m (Sun's radius)
T= 5778 °K (Sun's photosphere or Effective temperature)
a= 5.67051e-8 (Stefan-Boltzmann Constant)
d= 149597876600 meters (Earth's average distance, Mariner 10), 1 AU
f= flux or Insolation.
L= 4pi·R2aT4 = 4pi·d2f
Therefore, f=(R2aT4) / d2
Then ((6.955e8 m)2 (5.67051e-8) (5778°K)4) / (149597876600)2 = 1366.079 W/m2
(Which is only off by 0.1333% the so called satellite measured solar constant.)
This is the average. If you factor in the Earths's eccentricity (0.016710219), then the range is 1321.5430 W/m2 to 1412.9039 W/m2
