There has been quite high research going on in space science. Discovery of newer star and planets has been of wider research over their term.

A team of Brazilian astronomers has discovered two new planets which were found around the star which were similar to sun known as HIP 68468.

These two planets has been dubbed “super Neptune” and “super Earth” and are the first to be discovered by Brazilian astronomers since the discovery in 2015. It has been a planet similar to Jupiter, according to the Brazil’s G1 news website.

Discovery of 2 New Planets:

Astronomer Jorge Melendez who is a professor at the Institute of Astronomy, Geophysics and Atmospheric Science at the University of Sao Paulo and being head researcher.

It even said that one of the objectives of the team was to compare the solar system with other planetary systems.

Planetary environment located around HIP 68468 is quite different from the system which includes Earth. The mass of the newly discovered planets were quite similar to that of Earth’s and Neptune’s.

Planets rotate quite close to their stars and is suggesting that they might have migrated from a more exterior to a more interior region of their planetary system.

G1 further adding on the same says, “Super Neptune, called HIP 68468c, has a mass that is 50 percent greater than the planet Neptune. But while our Neptune is far from the sun (30 times the distance between the Earth and Sun), the orbit of the new planet is only 70 per cent of the Earth-Sun distance.”

Super Earth or the HIP 68468b is having a mass which is three times larger than that of Earth’s and its orbit is barely at 3 percent of the distance from Earth to the Sun.

It means that it is “practically stuck to its star”, HIP 68468 which is about 6 billion years old and 300 light years away from the Earth.

According to Melendez, this research is indicating that the star has HIP 68468 which has “swallowed” a planet due to the presence of higher levels of lithium.

It is an element which is quite abundant in planets, not stars. This discovery was made at the European Southern Observatory in Chile’s northern Atacama Desert.
