One-in-a-million: 'Super-Earth' discovered near center of our galaxy
Calling it"incredibly rare," New Zealand astronomers say that the planet"is one of only a handful that have been discovered with both size and orbit comparable to that of Earth," according to a statement.How does this distant world and its star compare to our neighborhood? According to the study, the super-Earth's host star is about 10% the mass of our sun, and the planet would have a mass somewhere between that of Earth and Neptune.
"Water could not exist in a liquid state and the likelihood of life would be very low," he said."Only a very few planets have been detected that may have suitable conditions for life." Study lead author Antonia Herrera-Martin, also of the University of Canterbury, said the planet was discovered using a technique called"gravitational microlensing."
The microlensing effect is rare, he said, with only about one in a million stars in the galaxy being affected at any given time.
