Our solar sistem


Mercury is a first planet in our solar system. Mercury goes around the sun the fastest of all the planets. Mercury has no moons. Mercury is named after the messenger for their gods. The planet Mercury moves quickly around the sun. That is how it got its name.


Venus is a terrestrial planet and is sometimes called Earth's "sister planet" because of their similar size, mass, proximity to the Sun and bulk composition. Venus is the second planet from the Sun. Venus completes an orbit every 224.7 days.


Earth is lthe third panet in our solar sistem. Earth has a moon its name is Luna.The Earth's rotation is slowly.
This deceleration is happening almost imperceptibly, at approximately 17 milliseconds per hundred years, although the rate at which it occurs is not perfectly uniform. This has the effect of lengthening our days, but it happens so slowly that it could be as much as 140 million years before the length of a day will have increased to 25 hours.


Mars is the fourth planet in the our solar sistem. Named after the Roman god of war, and often described as the “Red Planet” due to its reddish appearance. Mars is a terrestrial planet with a thin atmosphere composed primarily of carbon dioxide. The two moons of Mars, Phobos and Deimos, were discovered by American astronomers


Jupiter is the fifth planet in the our solar sistem.Named after the Roman king of the gods, Jupiter is easily the largest and most massive planet in the Solar System. Jupiter has a composition similar to that of the Sun: in fact consists primarily of hydrogen and helium with small quantities of other compounds, such as ammonia, methane and water.


It is the sixth planet of the Solar System in order of distance from the Sun and the second largest planet after Jupiter. The name derives from the god of Roman mythology, the god Jupiter. [


Uranus is the seventh planet of the solar system in order of distance from the Sun, its name comes from the greek god of the sky: Uranus.

Although it is visible to the naked eye, as the other five planets known since ancient times, it was never recognized because of its low light and its orbit particularly slow; it was discovered only 13 March 1781 by William Herschel, making it the first planet to be discovered through a telescope.


Neptune is the eighth and farthest planet in the Solar System, starting from the sun. The planet's name is dedicated to the Roman god of the sea

Discovered September 23, 1846 by Johann Gottfried Galle with the telescope of the Astronomical Observatory of Berlin. Neptune was the first planet to be found by mathematical calculations. The planet was discovered by just one degree from the expected point.


Pluto is a dwarf planet orbiting in the outlying regions of the solar system, was discovered in 1930 by Clyde Tombaugh and initially ranked as the ninth planet. Reclassified as a dwarf planet August 24, 2006.

After its discovery, the new celestial body was christened in honor of Pluto, the Roman god of the underworld.
