The sizes of the planets, Sun and Moon visible from Earth

Neptune has made only one revolution around the Sun since its discovery Neptune is the most distant planet in the solar system. It was discovered in 1846. It was the first planet discovered using maths: astronomers noticed that Uranus had deviated from its calculated orbit, which allowed them to assume the existence of another planet and then find it. An orbital year lasts 164.8 Earth years

Pluto's icy mountains and plains captured by the New Horizons spacecraft in July 2015 ❄️ The spacecraft was about 18,000 kilometres away from Pluto, about 15 minutes after its maximum approach to the dwarf planet.

If you photograph the Sun at the same time from the same angle during the year, its location in the sky will always be different. The path described by the Sun during the year has the shape of a figure eight. This phenomenon is called analemma. The highest position of the Sun on analemma corresponds to the summer solstice, the lowest - the winter solstice. Position in the middle of the "eight" sun takes twice a year, in mid-April and at the end of August.

Scientists have found alien life with a high probability. Now exoplanet K2-18b is the main contender for the presence of extraterrestrial life. - James Webb's half a billion dollar telescope is now actively studying the planet. - On K2-18b have already found signs of life - gas, which on Earth emits only plankton. - So it's likely to have a water ocean and a hydrogen-rich atmosphere. - Planet K2-18b is 2 times larger and 8 times heavier than Earth, and the year lasts 33 days. - The super-Earth is 120 light years away from Earth - that's very close on an astronomical scale. - If scientists confirm signs of life, we could be in for the biggest discovery in history

Jupiter is the only planet in the solar system that does not revolve around the sun. Jupiter does not revolve around the sun, but around an empty point in the space between it and the sun. This point is called the barycentre. This is because not only does the Sun exert an influence on Jupiter, but Jupiter, due to its impressive mass, exerts a gravitational influence on the Sun.
