A smaller moon of Mars
Deimos is a smaller and more distant Martian moon. Its diameter is only 12.4 km, although it is difficult to talk about the diameter in the case of su ...

Did you know?

Moon
The surface of the Moon is littered with impact craters because it does not have an atmosphere thick enough to destroy pieces of rock heading towards it.
The largest crater on its surface is the South Pole-Aitken Basin, it is 2500 km in diameter and 13 km deep.
Phobos
The distance of Phobos from the surface of Mars is only 2.76 times the radius of the planet.
Earth
Due to the Earth's rotation, the diameter of the equator is 43 km larger than the polar diameter.
The Earth is therefore a slightly flattened ball - this shape is called a geoid.
Earth
The length of the day on Earth is constantly increasing.
In the first million years of the Earth's existence, the day lasted only four hours. From the very b ...
Cosmos
The Solar System is located in the Milky Way.
Our galaxy ranks rather average, its diameter is 100 to 120 thousand light years. Perhaps a unique f ...
Aurora
It is believed that the aurora phenomenon may occur on all other extrasolar planets that have a magnetic field and a magnetosphere exposed to stellar winds.
The resolution of the telescopes does not make it possible to capture an image of this phenomenon, but the emission of radio waves accompanying the aurora can be detected using radio telescopes.
Moon
The Moon always faces the Earth with the same side.
This is because our natural satellite is in synchronous rotation with the Earth. A long time ago, th ...
Milky Way
Until 1920, most astronomers believed that the Milky Way contained all the stars in the universe.
Only observations made by Edwin Hubble made humanity realize that it is only one of many galaxies.
Cosmos
Each object in the sky is observed with a delay.
The farther away the celestial body is from the observer, the longer the light emitted or reflected ...
