A newly discovered planet light-years from Earth is just four times the mass of our home planet, making the second smallest extrasolar planet to be found to date.

Astronomers using the Keck Telescope in Hawaii discovered the alien world, called HD156668b.

The planet sits in a star system about 80 light-years from Earth in the constellation Hercules and orbits its parent star once every four days or so. It is the latest extrasolar planet to join the ranks of the so-called "super-Earths," worlds slightly larger than our own.

I like the whole idea of finding other planets similar to our own, it fills me with optimism. I wish they would tell us the type of star is is orbiting, and what kind of solar system it is in, ah, I guess they will eventually.

The only thing that I don't like about knowing stuff like this is how long it will take until we can actually go to another planet. We cannot even find funding to get a human to Mars...
