The closest planet outside our solar system orbits a young Sun-like
star only 10.5 light years away—so close that telescopes might soon
be able to snap pictures of it, new observations confirm.
About 1.5 more massive than Jupiter, the planet takes 7-years to
circle its star, Epsilon Eridani.
The giant gas planet was originally detected in 2000, when astrono-
mers noticed a rocking motion in the star which they attributed to the
gravitational tug of an unseen planet.
Astronomers recently confirmed the wobbles and the planet's existence
with NASA's Hubble Space Telescope.
Astronomers think enough starlight might be reflected off the planet
when it makes its nearest approach to Epsilon Eridani in 2007 for
Hubble and other telescopes to image it.
If moons circle the planet, they might have temperatures similar to
Earth's and possibly liquid water, said study team-member Fritz Ben-
edict at the University of Texas.
However, the planet's orbit takes it so far from its star that any oceans
on the moons would freeze.
However, life could potentially survive on such moons if they were
massive enough to retain a dense heat-trapping atmosphere like
Saturn's moon, Titan, Benedict added.

Imagine an earth 1.5 times the size of jupiter, that would be incredible.

It would be incredible yes, but it's also impossible.
And I honestly would'nt believe it.

There could be a planet that size with continents and oceans I think, I don't see why not.

But it would be hard for life on land to exist in that intense gravity, but perhaps there could be a rich ocean ecosystem.
