The Solar System Demystified

The sun and nine planets of our system orbiting.

It is general knowledge that our solar system is made up of a star, the sun, the eight planets, 146 moons, a bunch of comets, asteroids and space rocks, ice, and several dwarf planets, such as Pluto. The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Mercury is closest to the Sun. Neptune is the farthest.

Did you also know that the solar system is the gravitationally bound system of the sun and the objects that orbit it and that it formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud? A lot of people also believe that it came about after a big bang, a huge explosion. Hence, the big bang theory.

Now have you ever wondered about the solar system or asked questions like, what is actually in these planets? Other than earth, does any other planet support life? Do diamonds rain in Jupiter? What kind of gases are there in other planets? Is there solid ground like on earth? Has anyone really visited Mars? Can we actually have a honeymoon on the moon? Let us dig in this article to find out.

Mercury has a massive metallic core. It contains more iron than any other planet. Mecury might have some inner core just like the exterior that contains liquid metal. Venus’ insides are covered with a crust, its likened to be the same as 3,000 ft underwater on earth. It has a metallic iron core hot enough to melt lead and a thick rocky layered mantle that contains carbon dioxide, nitrogen, and sulphuric gases. Earth is the denser of the solar system, the inner core is made up of iron and nickel and is broken into tectonic plates that move as fast as your fingernails grow and let heat escape from the earth’s interior. Its crust is mostly made up of oxygen, silicon, aluminum, iron, and other minerals.

Mars is made up of rock and minerals with a core made up of iron, nickel, and sulfur. You can attribute the interior of Mars to soft rocky toothpaste, yeah brush your teeth with that. It has a thinner mantle than the earth, it contains volcanic dissolved rocks. The crust is covered with fine reddish dust that looks like talcum powder.

These first four planets are considered terrestrial because scientists say that the sun sent out energy and particles in a steady stream, called stellar winds and that these winds proved so strong that they blew off most of the gases of the four planets closest to the Sun, leaving them smaller, with only their rocks and metals intact. That is why they are called rocky, or terrestrial planets. The four outer planets were so far from the Sun that its winds could not blow away their ice and gases. They remained gaseous, with only a small rocky core.

They were made of more gas (namely hydrogen and helium) than the others to begin with, the sun’s gravity, having pulled closer the heavier materials in the original solar disk. For this reason, the first four planets are called the inner planets and the other four are called the outer planets.

Between the inner and outer planets lies an area filled with millions of asteroids — small rocky, icy, and metallic bodies left over from the formation of the Solar System. No planet formed in this area. Astronomers theorize that Jupiter’s gravity influenced this region so much that no large planet could take shape. Jupiter is 11 times the size (in diameter) of Earth and more than twice as big as all the other planets combined. It is almost large enough to have become a star. And no, diamonds do not fall in Jupiter. Matter of fact, the outer planets have the worst thunderstorms every single time with the gases interacting with themselves at very low temperature and high pressure.

Mars does not support life, in fact, Mars lacks an Earth-like atmospheric pressure. It is extremely cold with a temperature of -60 degrees Celsius. Be rest assured that upon stepping on Mars’ surface, you could probably survive for around two minutes before your organs rupture. Young ladies who expect the moon when they get married may one day have their wish. Astronomer Fred Whipple predicts that in the not too distant future, trips to the moon will replace the traditional journey to Zanzibar and Seychelles. Just how soon is anybody’s guess.
