Just 21 light years away, scientists find a ‘Super Earth’ that has make ups similar to our own EarthDaniel McCarthy (Author) Published Date : Aug 03, 2015 18:47 IST
A new super Earth has been discovered by Scottish astronomers at a distance of just 21 light years which is the closest to our solar system. The research is being lead by stargazers at Edinburgh and St. Andrews Universities for planets similar to earth that can sustain alien life.
The scientists joined hands with teams from around the globe for constructing a sophisticated gadget several years back to help them examine the planets further where ideal conditions for life could be present.
Presently, they have found a rocky planet that is closest to our Earth just outside our solar system. However, the Scottish astronomers say that it is pretty hot for supporting life on account of its proximity to the parent star.
This new Super Earth is just 21 light years away and was hidden in the northern hemisphere that is M shaped and within the constellation Cassiopeia.
The planet christened as HD 219134b is about 4.5 times in mass compared to our Earth and the radius is some 1.6 times and is it takes about 3 days for the planet to revolve around its star.
Scientists believe that this planet has a molten surface and does not constitute a habitable zone around its star which might support life.
Because this planet transits in front of its star, scientists have the rare chance of determining its composition. It is likely that the planet is a volcanic world with molten rock, residing in a system with a number of other super earths orbiting a dwarf and bright star.
It is a proximate planet with a significantly bright star and therefore means that any follow up in future with bigger telescopes will get easier though these are not expected to be habitable planets. explains Professor Ken Rice from Edinburgh University. He adds that it is petty unlikely there is any life form since is very close to the parent star and will be extremely hot. What is expected of the scientists in the longer term is the ability to characterize the planets with regard to its internal composition which has already been done and the composition of their atmospheres. In turn that could help us develop the technology to probe planets that could be habitable.
The professor also said that the Planet is like the earth in its composition as well as density but it is very very close to its parent star to make it habitable. It is also unlikely that there is any water on the planet though the rocky character of the planet is similar to our Earth.
