Pretty damn close I'd say. It must be a very small star because any planet orbiting the sun that quick would melt in a matter of minutes.

A planet that may be Earth-like but too hot for life as we know it has been discovered orbiting a nearby star. Further investigations demonstrate that the planet is a remarkable parallel to earth. It also developed a human-like life form and developed politics similar to the United States. Unfortunately, on that planet, socialists gained the upper hand and drove all business into the ground. The people of the planet had to continue burning trees and cow dung, which lead to the state we find the planet in today.
Shalom.

between 400 degrees and 750 degrees Fahrenheit Rampant book-burning and corresponding anti-environmental policies likely led to the conditions there...

I'm curious if the gravity of a planet is affected by it's densityThe short answer is yes. Gravity is a function of the mass of the body and the distance from the centre of mass. Therefore the surface of a less dense planet would be further from the centre of mass and gravity at the surface would therefore be lower.

Sounds right. I'd like to know more about it.

Actually, I don't have the math handy but I believe that a body with the density of rock and the volume of Jupiter would probably be a star, ignited by the pressure of all that mass. That's why rocky planets are small and the only large planets are the gas giants.

They estimated the surface temperature on the new planet at between 400 degrees and 750 degrees Fahrenheit. *************************************************************
That's earth like?
Perhaps they should have said: 'Venus like' - but that wouldn't have made an eye catching headline.

Ive been digesting this. It's all interesting to me.

I just can't believe that orbital period. It would have to be so close to the star that friction would quckly bring it down. The square of the orbital period is proportional to the cube of the orbital radius and inversely proportional to the mass of the central body, in this case the star.
Plugging in the 1/3 the mass and the 1.94 day period we get an orbital radius of 0.04406 * the earth's orbital radius about Sol, or about 4,083,172 miles. That seems plausible, but it is close. Mercury is just over 1/3 the distance from Sol that Earth is.

Gliese 876 is a small, red star with about one-third the mass of the sun. The researchers said this is the smallest star around which planets have been discovered. The usual problem with discovering 'small' extrasolar planets, is the wobble the they produce on their suns is too small to detect - but with the relatively small mass of Gliese 876, a smaller world would produce a greater wobble than we'll say that of a super giant, or even a star like our sun - I assume that's why they discovered a small world in this case.

Gravity is directly proportional to mass But also inversely proportional to the square of the radius. Thus a larger, but less dense, planet will have a lower surface gravity than another of the same mass.

Thanks for the calculations. That IS close! I wonder if they have enough data to determine if the orbit is stable?

they probably mean Earth-like because it ISN'T a gas giant....
