California / agencies :
NASA has spotted an "exoplanet" about the size of the Earth, orbiting a small star about 100 million light-years away.
Using the data of the space telescope (TESS), the agency spotted the planet called TOI 700 e orbiting the small dwarf star M TOI 700.
The planet is the fourth to be discovered around this star in a potentially "habitable" region, that is, one that is located at a distance that makes it possible for liquid water to exist on the surfaces of planets.
NASA said in a statement on Tuesday that its size is 95 percent of the size of the Earth and it is likely to be rocky".
Scientists have previously discovered three planets around this star called TOI 700 b, c and d, all of which are located in the potentially habitable zone.
The possibility of the presence of liquid water indicates that the planets could be, or may have once been, habitable, according to "CNN".
Emily Gilbert, a postdoctoral fellow at NASA's Jet Propulsion Laboratory in Southern California, who led the work, said:"This is one of the few systems with multiple, small planets and habitable zones. This makes the TOI 700 system an opportunity for further follow-up,"he said.
