THE COMETS ☄ — SteemCN

• The Comets:

Comets sometimes visit our Planetary System, attracted by the force of gravity. In their march they come very close to the Sun, spinning quickly behind it, and retreat again to appear new after long years. The appearance of comets is extremely curious: with the naked eye they seem bright stars; observed with the telesCopio show certain traces gos or characters "that facilitate their recognition. During the brightest season, the comet has a luminous head nosa in the shape of a star; from this head it floats a long ray of light, which it is the tail or hair. The most famous conetas and which appear with long intervals of lieli po are the so-called Donati and Halley. was discovered by him astronomer of this name, in Florence, in the year 1858 and when it was at a distance from the Sun of two hundred and forty million miles. "It remained visible for nine months, this time resulting at least part of what he uses on his long journey. According to the cartels that were made then, it will be visible again in two thousand years The story of Halley's Comet begins with the English astronomer Fa aundo Halley, its discoverer, in 1682. Halley discovered that the trajectory " of this comet was an ellipse, "traveled every seventy-six years approxl and that it would reappear in 1758, as it did indeed appear. Then it again became visible in 1834 and finally in 1910, the astronomers then showed that the comet would pass between Earth and e Sun, at a distance from Earth of fifteen million miles. and Halley's coneta walked away, proving with mathematical exactitude with which he followed his trajectory, previously determined, the incontestable truth of the laws of gravitation and movement of the stars.
