I used table format, using the basic help information and the Data Column Names information,
and did a quick filter cobble of "Rplanet<2 AND Tplanet<320 AND 5000<Tstar AND Tstar<6000"
This can be abbreviated "Rplanet<2 & Tplanet<320 & 5000<Tstar & Tstar <6000", but note
that 5000<Tstar<6000 is not legal according to the help (though I didn't try it, actually).
Note also that as noted on http://kepler.nasa.gov/Mission/discoveries/
, the temperature
computed for earth is 255K, assuming a basic rock at equilibrium. It is the greenhouse effect
mainly of water vapour which gives us the actual average temp of 288K.
The sun has a colour temp of 5500K, just greenish of yellow.
I also did a computation a while back on the relationship between gravity, density and radius,
and also found that earth is density rho(ave)5.5, being ~9 for the core and 3.5 for the mantle.
This means it is unlikely but possible to consider a planet with rho(ave) considerably lower
than earth's. The relationship is g=GM/R^2, M=(4/3)*rho*pi*R^3, so g=(4/3)G*pi*rho*R, if I'm doing
this right, and so R goes as g over rho. So I considered rho(ave)=3.5 with g constant, then R
goes *(5.5/3.5)=*1.6, so you would get 1g @ r=1.6Re. I personally wouldn't want a planet with
more than about 1.2g. As g goes as R and as rho, for the 3.5 density planet you could have R=1.9Re,
but for a far more likely density similar to earth's, you wouldn't want more than 1.2Re.
The planet I highlighted is the closest candidate yet; it has T=263K vs earth's 255K, its star
is 5283K vs our 5500K, so a bit on the orange side, and its radius is 1.45 Re, so we might weigh
anywhere from 1.3 to 1.6 times our normal weight on its surface, if it has formed in the manner
of our system's rocky planets. See http://en.wikipedia.org/wiki/List_of_Solar_System_objects_by_size
(The rocky planets and moons of our solar system divide distinctly between those with density around
that of earth @ 5.5, and those (all much smaller) with density ~3.5, such as our moon. The 5.5 density
is consistent with the aggregation of elements in the relative abundances typical of the sun and the
solar system as a whole (after shedding the lighter molecules of gases which cannot be held by these
small objects). The lower density moons have an anomalous elemental distribution which suggests they
may have a history similar to our moon, which is believed to have accreted from upper crustal material
from the earth which was shorn off by a collision, some time after the denser elements had concentrated
out of reach in its core. It is known that at least one planet which was large enough, and existed
long enough to fully differentiate into a crust/mantle and a core, was subsequently shattered, as
this is the source of the metallic meteorites. This would presumably have provided plenty of crustal
and mantle material from which these low density moons could have formed. All of this goes to suggest
that the earth's density is strongly likely to be typical for a planet of its mass or larger, until
the mass gets large enough to retain light elements, and thus no longer being a rocky planet, but a
small gas giant.)
