Supernova stars
About seven thousand years ago, a star suddenly exploded in a remote corner of outer space, dropping the outer layers of matter. A relatively large and massive star suddenly ran…

Birth of the sun
And now the nebula has acquired a completely different look. A huge dark, slightly flattened cloud rotates majestically in the middle, and around it at different distances floating in circular…

Asteroid shape and rotation

Asteroids are so small that gravity is negligible. She is not able to give them the shape of a ball, which gives the planets and their large companions, crushing and ramming their substance. An important role is played by the phenomenon of fluidity. The high mountains on Earth at the bottom “sprawl”, because the strength of the rocks is insufficient to withstand loads of many tons per 1 cm3, and the stone, without crushing, without breaking, flows, although very slowly.

On asteroids with a diameter of up to 300-400 km, due to their low weight, such a phenomenon of fluidity is completely absent, while on the largest asteroids it occurs extremely slowly, and even then only Continue reading

The history of the discovery of Pluto
In the 1840s, with the help of Newtonian mechanics, Urbain Le Verrier predicted the position of the then undetected planet Neptune based on an analysis of perturbations of the orbit…
