Jakarta –
When discussing outer space, of course, what is remembered is the vast empty space, including the four where our Earth stands.
The composition of space is very much starting from our solar system and there are still many galaxies that we do not know about.
Even though there have been many discoveries, human knowledge regarding outer space is still very minimal. The billions of galaxies, stars and planets in the solar system, of course, have not all been explored by our scientists. This causes science related to outer space to continue to grow.
However, detikers do you know that there are some unique facts related to outer space that are quoted from Arizona State University. Come on, see the unique facts related to outer space that you might not know!
10 Unique Facts Regarding Outer Space:
1. There is No Sound in Space
Do you know that outer space is very quiet and has no sound at all?
This is due to the absence of an atmosphere in outer space. The atmosphere itself is a medium so that the sounds created can travel and be heard. The absence of an atmosphere is what causes outer space to be very quiet.
2. The temperature of the hottest planet in the Solar System reaches 450°C
Uniquely, the hottest temperature of the planet in our solar system is not the planet with the closest distance from the solar system, namely the planet Venus. In fact, the hottest planet in our solar system is the planet Mercury with temperatures reaching 450° C. Why do you think that is the case, detikers?
The planet Mercury apparently does not have an atmosphere that can regulate temperature and cause large fluctuations.
This causes Mercury to have very hot temperatures and to be the hottest planet in the solar system.
3. NASA Space Suit Worth $12.000.000
The total cost of the space suits built by NASA in 1974 turned out to be a value of up to $12 million. A large part of that cost goes into manufacturing the suit’s backpack and control module.
If valued at today’s price, the suit will reach 150 million dollars or the equivalent of 2.2 trillion rupiah. A very fantastic number is not it?
4. The mass of the sun is 99.86% of the mass of the solar system
Even though the solar system has a very large mass, it turns out that most of its mass is filled with the mass of the sun, which reaches 99.86%. The sun itself consists mostly of hydrogen and then composed also by helium.
5. One Million Earths Can Be Mounted Inside the Sun
Did you know that the sun has a very large area? As a result of this area, it is estimated that the sun can accommodate as many as 1.3 million earths with the earth’s position squashed. However, if the earth retains its spherical shape, the sun can accommodate as many as 960,000 earths.
6. There are more trees on Earth than there are stars in the Milky Way
Even though it has a large enough space, it turns out that there are more trees on Earth than the number of known stars in the Milky Way.
The number of trees on Earth alone is known to be around 3 trillion trees while the number of stars in the Milky Way is around 100-400 billion stars.
7. Sunsets on Mars Are Blue
The moment of sunset is a moment whose beauty we often enjoy. However, did you know that sunsets on Mars have a bluish color?
NASA states that if we observe the setting sun on Mars, the setting sun will appear bluish in color.
This is due to fine dust that makes the blue color near the Sun much more visible.
8. There are more stars in the universe than sand on Earth
The size of the universe is of course much wider if we compare it to the Milky Way.
Scientists estimate the number of stars in the universe to be around 1,000,000,000,000,000,000,000,000 stars, or septillions.
Meanwhile, the estimated amount of sand on Earth is about seven trillion, five hundred quadrillion grains. This means that there are more stars in the universe than sand on Earth.
9. One Day on Venus Is Longer Than One Year
Venus is known to have a slow axis rotation that takes 243 Earth days to complete its day.
Venus’s orbit around the Sun is 225 Earth days. This causes a year on Venus to have 18 days less than one day.
10. Planets Made Of Diamonds
It is known that there is one planet which is made of diamonds and is twice the size of Earth. The nickname given is ‘Super Earth’ or ’55 Cancri e’. But the planet is most likely covered in graphite and diamonds.
