Astronomers have discovered the lightest exoplanets yet found.

Astronomers have identified two of the most unusual planets in the universe. Zamin.uz reported on this.

Although they are nearly equal to Jupiter in size, their density is so low that even cotton would be considered heavy. Specialists state that these planets orbit a star located approximately 1,110 light-years away from Earth.

According to scientific observations, they have been recorded as the lightest planets of their kind discovered to date. The discovery was made via NASA's TESS space telescope.

After the planets were initially identified, their orbit and density were precisely calculated using a series of telescopes on Earth. Scientists are calling these celestial bodies "super-puff" planets.

This is because they are primarily composed of hydrogen and helium gases, and their external structure is extremely light and bloated. While nearly 6,300 exoplanets have been confirmed outside the Solar System so far, fewer than 40 of them fall into this specific category.

For comparison, Jupiter, the largest planet in the Solar System, is nearly 35 times denser than these newly discovered planets. According to researchers, studying such planets helps enrich the understanding of how planets form and evolve in the universe.
