Betelgeuse is usually the tenth-brightest star in the night sky and, after Rigel, the second-brightest in the constellation of Orion. It is a distinctly reddish semiregular variable star whose apparent magnitude, varying between +0.0 and +1.6, has the widest range displayed by any first-magnitude star. Wikipedia

Asteroid nerves
The process of getting pieces from an asteroid from outer space to Earth and safely into the hands of scientists is tricky, to put it lightly.
Tachibana, who worked with the sample collection and capsule recovery teams on the Hayabusa2 mission, said that, unsurprisingly, "there have been many nerve-wracking things ...the safety recovery of the capsule and the rapid and safe preparation for the container opening in the curation chamber were actually most nerve-wracking for me. We had to open the container and take out particles as soon as possible."

Mercury is the first planet from the Sun and the smallest in the Solar System. In English, it is named after the ancient Roman god Mercurius, god of commerce and communication, and the messenger of the gods. Mercury is classified as a terrestrial planet, with roughly the same surface gravity as Mars.
It have 58 million km from the sun and 88 days for orbital period.
