 Four new planets are still in their teens, their life cycle could help scientists understand the Earth as it was before.

Overseas: Study leader Christina Hedges says the four newly discovered planets, 130 light-years from Earth, are in their teens and could tell scientists a lot. At the beginning of the year of the earth.

The exterior is known as TOI 2076 b, TOI 2076 c, TOI 2076 d, TOI 1807 B, orbit star TOI 2076 and TOI 1807 respectively. The study's lead author, Christina Hedges, said the newly discovered planets were two to four times the size of Earth and were still in the process of changing their lives.

"The planets in both systems are in transition or adolescence," Hedges, an astronomer at the Bay Area Environmental Research Institute and the Ames Research Center in Asana, said in a statement.

They are not newborns, but they are also unresolved. Exploring more about the planets at this young age will help us understand the older planets in other systems. The planets were discovered by NASA's Transiting Exoplanet Survey Satellite (TESS) north of Botita and Canes Venatici, respectively, 30 light-years apart.

Both stars are K-type dwarfs, more orange than the Sun and between 3,500 and 5,000 Kelvin, and the Sun's surface temperature is about 5,800 Kelvin. It is believed that the two stars were born in the same gas cloud about 200 million years ago.
