10 facts about space

1. All the planets of the solar system could fit inside the planet Jupiter

2. The red giant star Betelgeuse has a diameter larger than the orbit of the Earth around the Sun.

3. The duration of a full solar Eclipse does not exceed 7.5 minutes; total lunar Eclipse — 104 minutes.

4. Distance to the nearest (after the Sun) from the us star (Proxima Centauri) is 4.24 light years away.

5. If you put Saturn in water, it will float on the surface. The average density of Saturn is almost 2 times less than the density of water. If You can find a suitable glass (with a diameter of not less than 60 thousand km), you'll be able to check it out.

6. We all — people, houses, rivers and mountains are constantly moving in space at the speed of 530 kilometers per second. Within our galaxy we are moving at a speed of 225 km/h, and the Galaxy itself is hurtling into space at a speed of 305 km/h. Thus, as You read this sentence, the Earth moved You to a distance of 3 thousand kilometers.

7. The light of the Sun that You see is over 30 thousand years. The energy that we get from the Sun, formed at its core 30,000 years ago — so much time is needed to photons (particles of light) "broke" from the center of the light to the surface. After that, they reach Earth in just 8 minutes. The temperature of the solar core more than 13 million degrees, and all energy produced by them must first pass through numerous layers to the surface in the form of light and other radiation.

8. One of the most notable formations in the sky — the Big dipper. In fact it is not just a constellation, a so-called ASTERISM. This word refers to a visible cluster of stars, which is actually located very far from each other, in different parts of the milky way. We see these forms only due to the special location of the Earth relative to the asterism. The big dipper is part of another constellation called Ursa Major (the Great bear).

9. In order to start a ballpoint pen to write in zero gravity, the US has spent millions of dollars. But the Russian in space was done in pencil, and without making the design any changes.

10. Since 1980 lunar Embassy" vengeance is selling land on the moon. During this time, sold for 7% of the surface of the moon. The cost of 40 acres at the satellite of the Earth is 150 dollars. The buyer receives the certificate on the right to property and pictures of the site taken by American satellite.
