What are the sizes of the planets?

A planet differs from a star. The star is a giant ball composed of hot gases, radiant heat and light. The planet is much smaller in size. It emits no light, but rather, is warmed by starlight.

Let’s look at all the planets in order, starting with the one that is closest to the Sun. The nearest planet to Sun — mercury. The diameter of mercury is 4878 kilometers counts, i.e. equal to the Atlantic ocean. And that means mercury is much smaller than Earth.

The next planet is Venus. It’s almost the same size as our Earth. In diameter it has about 12 100 kilometers, and the Earth’s diameter is 12 kilometers 742,5. By the way, Venus rotates around the Sun in the opposite direction, from East to West. For Venus is Earth, then Mars.

Reddish color of the planet Mars has always distinguished it from other heavenly bodies of the Solar system. The diameter of this planet has 6780 miles. This is slightly greater than half the diameter of the Earth. Mars has always attracted the attention of scientists. Because the surface of this planet is visible to any shape, resembling canals. Out of all the planets of the Solar system except our Earth, on Mars it is most likely sushestvovaniya any form of life, maybe vegetable.

The next planet is Jupiter. 11,9 earth years required him to once around the Sun. Jupiter is the largest planet in the Solar system. Its diameter is 142 800 km, almost 11 times the diameter of the Earth.

Saturn is also a huge different sizes. Its diameter is 120 660 kilometers, which is equivalent to almost nine earth.

Uranium — neighbor Saturn is much greater than the Earth. Its diameter is no less 51 to 200 miles, and the planet itself is at an angle of 98 degrees about the nominal vertical axis. (Earth is at an angle of 23.5 degrees.)

The diameter of Neptune, the next planet in the Solar system, consists of 49 500 kilometers.

And finally, the least studied planet in the Solar system — Pluto, according to preliminary data, has a diameter of 3,000 kilometers. The distance separating Pluto from the Sun, is so great that there vyhlady our star is the only one of the brightest stars in the sky.
