1. The moon is gradually moving away from the Earth and year after year to become further 4 cm. One of the reasons for this phenomenon is the slowing down of the Earth's rotation period by 2 milliseconds per day. Scientists assume that the Moon is a fragment of the Earth, "beaten off" by a large cosmic body many billions of years ago.
2. The sun loses more than a billion kilograms of mass per second. This happens through the solar wind - a stream of particles moving from the surface of the Sun in different directions. One tiny particle of the solar wind is enough to kill a person at a distance of about 160 km.
3.When the planet Uranus was discovered in 1781, the scientist William Herschel was given the right to name his discovery. In honor of King George III, he chose the name Georgium Sidus (George's Star). Having said the following about this: “In the past, the names of the planets were given by the names of famous gods - Mercury, Venus, Mars, etc. In modern philosophical times, I want to act differently. If descendants ask - when was the last planet of the solar system discovered? The answer will be very honorable - During the reign of King George III. "
4. When two pieces of metal come into contact in space, they will merge to each other, if there are no oxides on their surface. This does not happen on Earth, because oxides are immediately formed on the surface in the atmosphere.
5. A car traveling at an average speed of 96 km / h would take about 48 million years to reach the closest star to us (after the Sun) - Proxima Centauri.
6. Ganymede, the largest of the moons of the planet Jupiter. Its discoverer is Galileo Galilei, who made it on January 7, 1610. Its size exceeds the planet Mercury by 8%. Ganymede's diameter is approximately 5, 269 kilometers.
7. The strongest magnets in the Universe are neutron stars. The magnetic field of a neutron star is a million million times larger than the magnetic field of the Earth. When a teaspoon is filled with the substance that makes up neutron stars, its weight will be approximately 110 million tons!
