Four small planets have been discovered by NASA, far beyond our solar system, according to scientists.

"The new discovery could provide new insights into how Earth evolved," NASA said.

According to NASA's latest report, one exoplanet, about twice the size of Earth, orbits the star TOI 1807 in just 13 hours, creating a "lava world" with a constantly evaporating atmosphere.

Three other exoplanets orbit the related star TOI 2076, which is about 130 light-years from Earth, NASA's report explained.

In a statement, University of Southern Queensland researcher George Zhou explained: "The planets were orbiting stars that were about 200 million years old — young in space terms."

"Moreover, the sun is about 5 billion years old and is about middle-aged in terms of stars out there."

"These planets are all toddlers, really energetic. It's a cool opportunity for us to take a look at planets when they're just formed," the statement added.

Dr. Zhou who was also a member of the team and co-authored a paper in The Astronomical Journal, affirmed: "For the other planets, the environment is still not Earth-like but it's slightly more benign."

It's worth mentioning that an international team of researchers confirmed the recent discoveries after they were picked up by NASA's Transiting Exoplanet Survey Satellite (TESS).
