astronomy space-With new space discoveries happening every week, it is not surprising that we want to have a list of interesting and amazing facts about space. Learning the truth about space is always fun. As time goes on, advances in technology have led humans to have more truth about space in the last century than ever before. In this article, we have searched for amazing and interesting things about space. Facts about solar system planets, moons, the Milky Way galaxy and …! We are sure that this article can be interesting and fascinating for you. So join us to invite you on a trip to the galaxy. We wish you a good and happy trip!

1. Mercury and Venus are the only planets in the solar system that do not have moons.

astronomy space-In total, there are 176 confirmed moons in the solar system that orbit the planets. Some of these moons are even larger than Mercury itself!

۲. If a star gets too close to a black hole, the star immediately shatters.

A team of astronomers observed a star in the center of the galaxy that orbited a black hole for 20 years. The star is now close enough to the black hole that its gravity exerts so much force on the star that it causes the star to explode and disintegrate.

3. Venus is the hottest planet in the solar system.

Many people think that Mercury is the closest planet to the Sun because it is the warmest planet. Venus, on the other hand, has a greenhouse effect due to the abundance of gases in its atmosphere, which keeps the temperature on the planet’s surface at 462 degrees Celsius, making Venus the hottest planet in the solar system.

4. Our solar system is about 4.6 billion years old.

astronomy space-To be precise, 4.571 billion years! Scientists believe that after 7.5 billion years, the surface of the sun will expand so much that it will swallow the earth!

5. Enceladus, one of Saturn’s moons, reflects 90% of sunlight.

Because the moon’s surface is covered in ice, it reflects more sunlight than it absorbs. As a result, the temperature in this month reaches -201 degrees Celsius.


6. The highest mountain discovered is Mount Olympus, which is located on Mars.

The height to the top of this mountain is 25 km and this height is about three times higher than the height of Mount Everest.

7. The Whirlpool Galaxy M51 was the first spiral celestial object to be discovered.

The galaxy’s large, spiral arms are made up of large lines of stars and gas along with dust. These arms act as galaxy star-forming factories. They compress hydrogen gas to form new star clusters.

8. One light-year is equal to the distance that light travels in a vacuum in one year.

Light travels at a speed of 300,000 kilometers per second; So one light-year equals about 500,000,000,000,000, 9 kilometers!

9. The size of the Milky Way is 105,700 light-years!

astronomy space-It takes 450,000,000 years for an advanced, modern spacecraft to reach the center of the galaxy!

10. The sun weighs 330,000 times more than the earth.

The sun is 109 times the diameter of the earth and is so large that it can accommodate 1,300,000,000 planets! In fact, the sun is so huge that it covers 99.85% of the volume of the solar system.

۱۱. The wind does not blow in the moon.

Because there is no wind on the surface of the moon, the footprints left by the astronauts never disappear.

۱۲. Due to low gravity, a person who weighs 100 kg on Earth will weigh 38 kg on Mars.

When sending robots to the surface of Mars, scientists take this into account and build them so that they are heavier and more portable.

13. 79 known moons orbit Jupiter.

Jupiter is the planet with the largest moon in our solar system, and it also has the largest moon in our solar system. This month is called Ganymede and is 5,262 km in diameter. This moon is larger than the planet Mercury and can be seen with a simple telescope.

۱۴. A Martian day lasts 24 hours, 39 minutes, and 35 seconds.

Because you would probably think that a year on Mars would be less than a year on Earth, right? But it is wrong! Because Mars orbits the Sun more slowly than Earth, Mars is actually 687 days a year!

۱۵. NASA’s LCROSS satellite has transmitted evidence of water on the moon.

While there can be no water on the surface of the moon, scientists believe that water can exist in the lower layers of the moon in the current conditions in the form of icy ice at the two poles of the moon.

۱۶. The sun rotates a full circle every 25 to 36 days.

For us on Earth, every time the earth revolves around us is equal to a full day. While a full cycle around the sun takes 25 to 36 Earth days.

۱۷. Earth is the only planet not named by the gods.

No one knows what the earth is called. It is only known that it is derived from two old English and German words.

۱۸. The tide is caused by the gravitational pull of the moon and sun.

This phenomenon is because the tidal force of the moon causes the earth and water on it to incline towards the moon. This tendency creates the largest tidal currents.

19. Pluto is smaller than the United States.

If you want to go around the equator on Pluto, this distance is equal to the distance from London in England to Denver in America.

20. According to mathematics, white holes are possible. However, no white holes have been found so far.

A white hole is a hypothetical region in space-time where nothing can enter from outside, although matter and light can escape. Basically, a white hole is the opposite of a black hole into which matter and light can enter, but even light cannot escape.

planets of the solar system
The solar system is made up of all the planets orbiting the sun. In addition to planets, this system includes satellites, comets, asteroids, planetary microcontrollers, and dust and gas. In a situation where the solar system has eight planets but more than 100 worlds.
