Size comparison of Planets and Stars

Comparative sizes of some well-known space objects

Surely everyone at least once in my life come across another list of natural wonders, which lists the highest mountain, the longest river, the driest and the wettest regions of the Earth and so on. Such records are impressive, but they fade tightly in comparison with the sizes of space objects. Here’s to them we will now see.

Mercury is the smallest planet of terrestrial group. The radius of mercury is 2439,7 + 1,0 km 0,055 Mass of the planet earth. Area 0,147 earth.

Mars is superior in size only to the mercury. The mass of the planet equal to 10.7% of the mass of the Earth. Amount equal to 0.15 volume of the Earth.

Venus is closest to Earth on the indicators. The orbital period of 224.7 earth days. Amount equal 0,857 earth. Weight-0,815 earth.

The ground – fourth in the list of largest after mercury.

Neptune – mass Neptune bigger than Earth at 17.2 times.

Uranus – Neptune a little more.

Saturn is classified as a gas giant along with Jupiter, Neptune and Uranus. The radius of the planet 57316 + 7 km Weight-5,6846 x 1026 kg.

Jupiter is the largest planet in the Solar system. Classified as a gas giant. The radius of the planet 69173 + 7 km Weight-1,8986 x 1027 kg.

Volve 359 star removed 2.4 7,80 parsecs or light-years from the Solar system. Faint red dwarf which is not visible to the naked eye. Weight 0,09-0,13 Solar masses. Radius-0,16-0,19 radius of the Sun.

The sun is the only star of the Solar system. The mass of the Sun is $ 99,866% of the total mass of our Solar system, exceeds the mass of the Earth’s 333,000 times. The diameter of the Sun is 109 times the diameter of the Earth. Volume-1 303 600 volumes of the Earth.

Sirius – the brightest star in the night sky. Located in the constellation Canis major. Sirius can be seen from any region of the Earth except the most Northern. Sirius is 8.6 light years from the Solar system. Sirius our Suns more than twice.

Pollux is the brightest star in the constellation Gemini. The stellar mass of 1.7 + 0.4 mass of the Sun. Radius-8.0 mass of the Sun.

Arcturus is the brightest star in the constellation of Bootes. If you look up into the night sky, the second brightest star will be Arcturus.

Aldebaran – the brightest star in the constellation of Taurus. The mass is 2.5 Solar masses. The radius 38 of the radius of the Sun.

Rigel is the brightest star of the constellation Orion, the blue-white supergiant. Rigel is at a distance of 870 light years from our Sun. The beams 68 times more than our Sun, and the luminosity in 85 000 times stronger than the solar. Rigel is one of the most powerful stars in the galaxy. Mass of 17 Solar masses, the radius is 70 Solar radii.

Antares star is in the constellation of Scorpio and is considered the brightest in this constellation. Red supergiant. The distance of 600 light years. The luminosity of Antares stronger solar 10,000 times. The stellar mass is 15-18 Solar masses. With such great size and such a small mass, it can be concluded that the density of stars is very low.

Betelgeuse – a red supergiant in the constellation Orion. Approximate distance to stars light years 500-600. The diameter of the star exceeds the diameter of the Sun is about 1000 times. The mass of Betelgeuse is 20 Solar masses. The brightness of the solar stars exceeds 100,000 times
