JAKARTA, KRJOGJA.com – Astronomers from the University of Warsaw in Poland have identified two planets wandering around the galaxy, which do not revolve around the stars. This planet seems strange because there are no stars or sun that illuminates them.

Reported by Digitaltrends on Sunday (11/11/2018), the debate has reached the world of astronomy for years. The presence or absence of a wandering planet is still a mystery.

It is said to be a wandering planet because they do not have stars that illuminate them. They are very difficult to find because they are almost always dark. However, a technique called gravitational microscopy allows researchers to locate planets by seeing when a planet is coming between distant stars and Earth.

When this happens, the planet acts like a lens, deforming the light it can see from the stars when it reaches Earth. This shows that a large body like a planet passes in front of a star and the body size can be estimated by the magnitude of the deformation.

Two planetary wandering or fake planets are called OGLE-2017-BLG-0560 and OGLE-2012-BLG-1323. It was named because experiments of the Optical Gravitational Lensing Experiment (OGLE) were found.

The first planet to be detected, OGLE-2017-BLG-0560, was detected in April 2017 and can range from one to twenty times the mass of Zeus.

Data from the planet led scientists to look back on their old research data for similar items, where they found a smaller OGLE-2012-BLG-1323, which was first recorded in August 2012. (*)
