Planet Similar to Earth. Astronomers Have Announced the Discovery
Scientists have found evidence of a planet that is very similar to ours. Discovery was about the exoplanet revolving around a host star in the center of the Milky Way, about 25,000 light-years away from Earth.
The report of the specialists was published in the Astronomical Journal. At the moment the planet is called OGLE-2018-BLG-0677, scientists have not found a name for it yet. Researchers from the University of Canterbury, New Zealand, reported that the rocky planet is similar to Earth in orbit.
NASA estimates that out of 4154 confirmed exoplanets only about a third were similar to Earth on various parameters. So far, astronomers have not found a single exoplanet that is so similar to ours.
The mass of the new rocky exoplanet is 4 times more than the mass of the Earth. The supposed value is estimated to be something between the mass of the Earth and Neptune.
The exoplanet rotates around its star at a distance which is determined between the orbits of Venus and Earth around the Sun. One year on it lasts about 617 days. The mass of the host star around which it rotates is very small.
