Interesting discovery of strange planets outside the solar system

So far, humans have discovered more than 400 extrasolar planets (exoplanets) in the universe. Here are interesting facts about the most beautiful exoplanets that humans have ever known.

1. Why NASA never wants to send people to Venus
2. The new discovery of life on planet GJ 1132b, "super-Earth" is 39 light-years away

On May 30, 1993, the Methuselah planet was discovered deep inside the core of a spherical cluster of stars formed shortly after the Big Bang explosion and officially recognized on July 10, 2003.

Methuselah is the oldest planet found with a lifespan of about 13 billion years, three times the life of the Earth (about 4.5 billion years) and younger than the universe for only about 1 billion years.

The planetary system is closest to the solar system

On August 7, 2000, a system of planets consisting of Epsilon Eridani b and Epsilon Eridani planets orbiting a parent star named "Epsilon Eridani" was discovered. This is the planetary system closest to our solar system, about 10 light-years away.

This planetary system, has two asteroid belts, one between Epsilon Eridani b and the mother star, one outside Epsilon Eridani b and Epsilon Eridani c (this is also the dust ring outside of Epsilon Eridani c and is believed to be the result of collisions between comets outside the solar system.

The most difficult planet to discover

50% of star systems in the universe will have 2 or more stars. Therefore, if we awaken in space there will be a chance to see the two Suns growing together, which cannot happen on Earth, our Solar System is also a star system but only a single star Best.

System 91 Aquarii consists of 5 stars and in November 2003, scientists discovered the existence of a giant gas planet called 91 Aquarii Ab. This gas planet is difficult to detect because it is in a multi-star system, and may not be possible if there is another star nearby. Therefore, it became one of the rare planets discovered.

The star system has the most planets
