Astronomers discover two wandering planets, stars that do not orbit


<! –


JAKARTA, – Astronomers at the University of Warsaw in Poland have identified two wandering planets in the galaxy that do not orbitate around the stars. This planet seems strange because there are no stars or sun that will illuminate them.

Reported by Digitaltrends on Sunday (11/11/2018), the debate echoed in 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 have no stars to enlighten them. They become very hard to find because they are almost always dark. However, a technique called gravity microlensing allows researchers to identify planets by seeing when a planet comes between distant stars and Earth.

When this happens, the planet acts as a lens, distorting the light that can be seen from the stars when they reach Earth. This shows that large bodies, such as planets, pass in front of the stars, and the size of the body can be estimated from the magnitude of the distortion.

Two planetary mistakes or dishonest planets are called OGLE-2017-BLG-0560 and OGLE-2012-BLG-1323. Name this because it found an Optical Gravity Experimental Survey (OGLE).

The first detected planet, OGLE-2017-BLG-0560, was detected in April 2017 and may be between one and twenty times Jupiter's table.

Evidence on the planet has led scientists to review their old research data for similar evidence, where they found a smaller OGLE-2012-BLG-1323 that was captured for the first time in August 2012. (*)
