How about a planet that is close in size and mass to Earth?

Last summer a team of astronomers discovered a planet, dubbed MOA-2007-BLG-192Lb, that was only three times the size of the Earth.

Now, upon a reanalysis, scientists believe the planet might be much smaller. From New Scientist:

Initially, the team believed that this host star was a brown dwarf – an object too puny to sustain nuclear fusion, as normal stars do. That suggested MOA-2007-BLG-192-L b weighed 3.3 Earths.

But more recent observations suggest the parent star is actually heavier than first thought — a type of star called a red dwarf, team member Jean-Philippe Beaulieu of the Paris Astrophysical Institute reported last week at a meeting of the Royal Astronomical Society in London.

That suggests the planet weighs just 1.4 Earths. In size terms, that makes it a near twin of our own planet, closer in mass than any known planet except Venus.
