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... GabrielVelasquez (talk) 10:04, 13 January 2008 (UTC)[reply]

Yeah, seeing that it was basically Earth's orbit around a frickin' SUBGIANT made me wonder, too. I wonder if one of the astronomers who found it was first to make the determination that /epsilon Reticuli had Sol's habitable zone and, if so, which formula he used. At any rate this planet is cited alongside genuine "water cloud jovians" to this day. --Zimriel (talk) 02:17, 22 August 2008 (UTC)[reply]

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

I like this chart. I'm certainly going to steal that and throw it into Talk pages here and there. I'm not quite brave enough to face down the deletionists on main pages, but given time... -- Zimriel (talk) 02:10, 22 August 2008 (UTC)[reply]
