Celestial bodies

To observe the celestial you will probably needa telescope, because bright heavenly bodies, which could be observed with the naked eye, in the sky is very small - you can see only a small part of the stars and planets. Therefore, you can make a telescope with your own hands or you can purchase a ready-made device.

Stars

Stars can be easily observed in anycloudless night - they like a scattering of precious stones decorate the dark velvet of heaven. However, if you look at the stars with the help of even the weakest telescope, you can see tens of thousands of stars.

The star is the heavenly body in which thethe thermonuclear reaction of the conversion of hydrogen into helium, with the emission of a colossal amount of heat and light. Thanks to the light, the stars are visible to many millions of kilometers.

Depending on the temperature of the surface, luminosity, mass, chemical composition, spectral class, stars are divided into classes and groups.

The nearest star to the Earth is, of course,The sun. The sun belongs to the class of yellow dwarfs and is the only star in the solar system. Among the other closest to the Earth stars Proxima Centauri, Alpha Centaurra, Sirius and others.

With the naked eye on a clear clear night sky, you can observe up to 6000 stars: 3,000 in each hemisphere.

Planets

The planet is a celestial body of round shape thatRotates in orbit around the star or its remains. In the solar system, according to the latest classifications, there are 8 planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Pluto, considered until 2006 the ninth planet of the solar system, is now classified as a dwarf planet.

The planets are divided into large (gas giants) and small (earth-like). The first four planets from the Sun are small, the other four are large. The largest planet of the solar system is Jupiter.

Observe these celestial bodies as a telescope,and with the naked eye. Thus, the planets of Mercury, Venus, Mars, Jupiter and Saturn are clearly visible. In the amateur telescope, you can observe light and dark stripes on Jupiter and its Great Red Spot. Saturn can observe rings, satellites, and Mars and Venus have phases like the Moon.

Comets

Comets are rather rare celestial bodies. The orbit of rotation of the comets around the Sun is much longer than the orbits of the planets of the Solar System. Comets consist of a solid ice core surrounded by a shell of gases - as the comet approaches the Sun, the temperature of the gases rises and the shell becomes similar to a beautiful bright tail.

In total, about a thousand comets are known to mankind. Comet Halley - the most famous of all comets, it can be observed fairly close to the Earth only once in 100 years.

Observe these celestial bodies best in a telescope - only very rare specimens are visible to the naked eye.

Heavenly bodies in the sky - a huge array,besides they are in constant motion. Therefore, to observe different celestial bodies you will need not only a telescope and a clear cloudless sky, but also a map of the starry sky. Without this map, it will be more difficult to find the desired heavenly body.
