Discovering strange planets that have 4

Astronomers discovered a new planet about 125 light-years from Earth to four Suns.
Recently, the observation results obtained from the Palomar Observatory, San Diego, Calif., USA have helped the experts find an amazing discovery: a new planet in the universe illuminated by 4 Sun.

Specifically, this planet and its 4 Suns are collectively referred to as 30 Ari. This is a 4-star system and a planet about 136 light-years from Earth, of which the distance from the main planet to the Earth is 125 light years.

A special feature of the planet, is that it is in the orbit of 4 different Sun. The distance from one planet to the nearest Sun (called 30 Ari B star) is nearly 30 times the distance from Earth to the Sun (nearly 4.4 billion km). The estimated time to complete a rotation around 30 Ari B of the main planet is 355 days.

In terms of size, the Sun 4 planet is about 10 times bigger than Jupiter but there is no surface that allows spacecraft to land. In fact, it was discovered a few years ago. However, astronomers could only see 3 Suns around the planet.

Until recently, with the application of the Robo-AO observation system combining PALM-3000, the fourth Sun of the main planet was discovered. Thereby, 30 Ari became planetary systems with 4 second Suns discovered in the universe. The first planet possessed similar properties, which was KIC 4862625 discovered about 3 years ago.

KIC 4862625 planetary system was discovered in 2012

Currently, scientists are continuing research to decipher this new planetary system. In particular, experts focused most on the problem: why can a traction force of 4 different Suns be able to keep stable?
