TOI-561 b is a super planet Earth orbiting a star 250 million light years away. It is 1.5 times the size of Earth and lasts 10.5 hours a day. However, the most interesting thing about the planet is its age. Astronomers have estimated that the star system in which the planet is located formed 10 billion years ago, and it is not much later than the universe itself.

According to the latest calculations of mathematicians and astronomers, it is assumed that the age of the universe is about 14 billion years. For comparison, our solar system and Earth were formed “only” 4.5 billion years ago.

The TOI-561 star system and its three planets (TOI-561 b, TOI-561 c and TOI-561 d) were discovered as part of the TESS mission. It is a space telescope in orbit around the Earth. Its mission is to observe distant stars and look for the moments in which they “flash”. Flashes, instantaneous dips in the star’s light strength, mean the planets are moving in front of them. In this way NASAIt searches for extrasolar planets where life-sustaining conditions may exist.

TOI-561 b is referred to as Supersemia, Which is a rocky planet larger than Earth. However, due to its proximity to its star, the living conditions did not appear there. The temperature on the planet is over 2,200 degrees Celsius, and on the constantly lit side of the star, an ocean of magma is raging.
