There is no planet named Gliese 581g, 581d

One of the most potential candidates for Earth 2.0, Gliese 581g is just an illusion of the universe, while its companion Gliese 581d is not real either.

When discovered for the first time in 2010, Gliese 581g created a cheerful mood among astronomers because it looked very much like Earth in terms of size and surface temperature.

At that time, experts said this was the first planet outside the solar system in the Goldilocks area around the central star, which is not too hot or too cold, suitable for developmental life.

Recently, however, researchers from Pennsylvania State University (USA) have rejected Gliese 581g's existence, claiming that it is simply a trick of light due to magnetic field bursts. nearby star.

They also eliminated the existence of another planet in the same star system, named Gliese 581d, which was declared discovered in 2009, according to Space.com.

Fortunately, Gliese 581, 22 light-years from Earth, still has three other planets confirmed, but no planet in the area can nourish life.
