The nearest star that can be seen with the naked eye is called Alpha Centauri. It’s 4.36 light years away and can be seen from the southern hemisphere. However, the nearest star to Earth is 4.24 light years away. Its name is Proxima Centauri and it is so faint that you cannot see it with the naked eye.

The Mohs scale of mineral hardness was created in 1812. It ranges from talc, which is number one on the scale, to diamond which is number ten. Silver is between 2.5 and 3. Iron is between four and five. Glass is between six and seven. So silver is the softest of the three materials and glass is the hardest. The most common of these three gases in the atmosphere is nitrogen. After that comes oxygen. Hydrogen is less common than oxygen and is the least common of these three gases.

So far the hottest temperature recorded on Earth was at a place called Al Azizyan in Libya. The temperature reached a record of 58° Celsius.
