Astronomers have discovered that the pattern of the Solar System is found everywhere in the universe.
It assumes a star in the middle near which telluric planets (“planete telurice”) orbits, that are smaller solid
planets composed of stone and metals. Near the Sun there are: Mercury, Venus, Earth and Mars. Farther from
the star, gas planets (“planetele gazoase”) are orbiting. They are larger and were the first discovered outside
the Solar System. Around the Sun the gas giants are: Jupiter, Saturn, Uranus and Neptune. Frequently in the
universe, one or more gas giants ignite, becoming stars. For example, The Polar Star (“Steaua polară”) is one
such example of a multiple star.

Did Since it’s discovery back in 1930 until 2006, Pluto was
you considered the 9th planet of the Solar System. It is in reality
know a dwarf planet, so far away from sun that it need 248 years to
...? circle the Sun .
Many other wonderful things are about to
discover about the Universe, since at the end of 2021
the Space Telescope was launched James Webb.
Although it has only half the mass of Hubble, it has
far superior technology. He is expected to deliver
images of the first stars and galaxies that lit up in the
universe more than 13 billion years ago. He will help
us better understand the formation of stars, planets
and the life’s appearance.

Our planet is one of the 8 of the Solar System located next to several hundred billion stars in the Milky
Way galaxy, a galaxy that composes alongside several hundred or perhaps trillions of galaxies the Universe.
ÎIn conclusion, comparing to the Universe, our Sun is as big as a grain of sand relative to all the grains
of sand on all the beaches of the Earth.
