Space has always been a mysterious thing for most of us, and even though humans try so hard to discover new things in the space, there never seems to be an end to it. There are millions of things which are yet to be explored in space, and the following are some of the things you might not know about space:
Mercury is not the hottest planet:
Just because mercury is the closest planet to the sun, it does not mean that it is the hottest planet in the solar system. Many people blindly think that mercury is the closest planet in the solar system, but that is not the case. Venus which is the second closest planet to the sun happens to be the hottest planet in the solar system. Now you might be wondering why this might be the case, but if you take a closer look, you will come to know that Venus has a big and thick atmosphere which traps all the heat inside and makes Venus the hottest planet in the solar system. The entire concept is quite similar to how greenhouse gasses work in the earth. Heat gets trapped into the atmosphere, and it will not be able to escape and thus makes that planet the hottest in the solar system.
Pluto is smaller than the USA:
We all might be thinking that all planets are massive and magnificent. But when you take a closer look, Pluto is much smaller than the United States of America. We knew that Pluto was the smallest planet in the solar system, but we never knew that it would be smaller than the USA.
Pluto does not mark the edge of our solar system:
We all thought that the Planet Pluto marks the edge of our solar system, but that is not true. Our solar system is so huge, and the edge of our solar system is so much further away from our last planet. Today, scientist do not consider Pluto even as a planet and they believe that there are so many objects which are present beyond Pluto which is yet to be discovered.
Earth consist of many rare elements:
When you take a look at the composition of the earth, it is made up of iron, silicon, oxygen, magnesium, sulfur, calcium, nickel, sodium and aluminium. Such elements are merely traced elements in the space, but the earth is composed of such rare elements.
Rocks of Mars are present on Earth:
Yes, there are rocks of Mars present on the Earth, and the fun fact is that we did not bring those rocks from Mars. Scientists believe that meteorites would have blasted near mars and due to a volcanic eruption or collision, it would have hit the surface of the Earth.
