13 facts about Deimos
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?

Ganymede
Ganymede was examined closely by the spacecraft Pioneer 10 and 11, Voyager 1 and 2, New Horizons, and Galileo.
Amber
Amber often contains remains of insects, crustaceans, spiders, as well as plants.
The genetic material of organisms trapped within the amber is dissolved, so there is no possibility of recreating millennia-old creatures, such as dinosaurs, plainly out of the remnants from amber.
Titan
The closest Cassini’s flight around Titan took place at an altitude of 880 km on June 21st, 2010.
Its aim was to check if Titan has its own magnetic field. As it turned out, it does not have a clear ...
Milky Way
The disk of dark matter surrounding the Milky Way is about 2 million light-years in diameter.
It interacts with visible matter only gravitationally and remains invisible and undetectable in any other way. It is estimated that 90 percent of the mass of the Milky Way is dark matter.
Cosmos
The development of the universe can be divided into five stages.
The very early universe lasted only a picosecond, during which time the laws of physics that we know today had not yet developed.
Aurora
The Aurora Australis appears within the Earth's south magnetic pole.
The phenomenon can be observed in Tasmania, a mountainous island about 300 km south of the Australia ...
Titan
So far, more than 80 lakes have been discovered on its surface.
The seas and lakes of Titan are filled with liquid hydrocarbons.
Enceladus
The closest Cassini flyby over the surface of Enceladus took place in October 2015.
The probe, moving at a speed of 35.000 km/h, examined the composition of the material ejected by the geysers.
Earth
Most people live in the northern hemisphere.
This is because the Northern Hemisphere accounts for 68 percent of all landmass. It is estimated that in the future up to 90 percent of the population may live in this part of the globe.
Cosmos
There are about 200 trillion galaxies in the universe.
Each has a different composition and size. The largest galaxies can span up to 2 million light years.
