Our Solar System is the humanity cosmic backyard. Very tiny when compared to the Universe. But compared to our planet, it is vast.
Solar System appeared 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. The vast bulk of the Solare system’s mass is in the Sun, with most of the remaining mass contained in Jupiter. This planet and Saturn are gas giants, mainly formed of hydrogen and helium; Uranus and Neptune are ice giants. The four smaller innermost planets, Mercury, Venus, Earth, and Mars, are terrestrial, being principally formed of rock and metal. The Solar System also includes smaller space objects.
Biologist Eleanor Lutz scrupulous mapped out each known space object in our solar system over ten kilometers (about 10000 asteroids).
When mapping the space objects, ELutz noted that our solar system isn’t arrayed in linear lengths. Instead, it is logarithmic, with exponentially more space objects located close to the sun. Eleanor Lutz used this observation to space out their different orbits of the lighting thousand space objects in her map.
The Solar System
Since the beginning of space exploration, specialists realized that spacecraft could collect essential information about the different planets in our solar system. As a result, the U.S. and the USSR began to send automatic spacecraft to the other worlds in the late 1950s.
But even now, in the 21st century, the Solar system is still little explored. National Geographic has made a great map that shows the history of exploration of our solar system.
