Scientists are now analysing the entire data in depth to create a complete map of the temperature around the planet and better understand the composition of its atmosphere.

In a major discovery, scientists using NASA's James Webb Space Telescope have found the strongest evidence so far that a rocky planet outside our solar system has an atmosphere.

According to NASA, the finding is important because such small, extremely hot planets were earlier believed to be unable to hold on to thick layers of gas.

This planet, TOI-561 b, belongs to an extremely rare category called ultra-short-period exoplanets. It is approximately 1.4 times larger than Earth and orbits its star in less than 11 hours. 

The planet is located very close to its star, less than a million miles away. Its star is slightly smaller and less hot than the Sun.

Due to this proximity, TOI-561 b is tidally locked, meaning only one side of it is always facing the star. This permanently dayside of the planet is extremely hot, where rocks are likely to melt and an ocean of magma may be spread across its entire surface.
