3 Space Facts the you Should Know
The beauty of the space is one thing that keeps the human mind thinking. This is because of all the natural features like stars that occur during different times of the year on the clouds. Humans for a long time have been on a mission to uncover the mysteries of the space with most scientists coming up with very good results. The space is characterized by the presence of different bodies like stars and planets. But not too much is understood about the space on a factual foundation. This is attributed to the fact that there have been so little space exploration expedition. This however doesn’t follow that there aren’t any details about the distance. Below are some of the important space facts that you should know.
At the center of the universe you will find the sun. The sun contains matter up to one million times the size of the earth. With this feature, the sun becomes on of the most important body in the universe. In addition to this, the sun earth orbits the sun. Bearing this in mind, it’s necessary to say that sunlight makes up to 99. 8 % of the entire universe.
It’s also important to notice the fact that the most popular planet isn’t one which is nearest to sunlight. The nearest planet to the sun is mercury, as we understand from geography. One of the substantial characteristic that doesn’t make mercury the hottest planet is the simple fact that it doesn’t have an air. This leaves it warm during the day if its surface is totally exposed to sunlight. With in this period, the typical temperature can grow up to 425 degrees Celsius. Nonetheless, at night the planet gets cold as low as -180 degree Celsius. The hottest planet in space is Venus due to the ability of its thick clouds to trap the heat coming from the sun making it hot at all times. It can reach up to 500 degree Celsius in hotness.
Quite an interesting fact about metals in distance is that it sticks together when two of these come together. The process in which they bond is referred to as cold welding. This happens as a result of the absence of air in space. In the world, this procedure doesn’t happen without specific treatment. This is due to the availability of oxygen in atmosphere. Nevertheless, cold welding is employed in a number of the manufacturing process in the world, under technical conditions. Those equipment put on by astronauts do not get affected by this because of the coat of oxide put put in them.
