Top 10: huge space objects

Oceans, of course, is extensive, and the mountains are impressive for its size. 7 billion people is also not a small number. Since we live on planet Earth (whose diameter is 12742 km), it is easy for us to forget how we, in fact, tiny. In order to realize it, all we need to do is look into the night sky. Looking at it, it becomes clear that we are just a speck of dust in an unimaginably vast universe. The list of objects below will help to see the greatness of man in the future.

The largest planet (by diameter 142.984 km)

Jupiter is the largest planet in the Solar system. Ancient astronomers named Jupiter king of the Roman gods. Jupiter is the 5th planet from the Sun. Its atmosphere consists of 84% hydrogen, 15% helium with small admixtures of acetylene, ammonia, ethane, methane, and water vapor hospita. The mass of Jupiter is 318 times the mass of Earth, and its diameter is larger than the earth 11 times. The mass of Jupiter is 70% of the mass of all other planets of our solar system. The volume of Jupiter can hold 1300 planets the size of Earth. Jupiter has 63 known satellites (moons), but almost all of them are very small and dim.

The largest object in the Solar system (diameter 1.391.980 km)

The sun (Sultanuizdag-dwarf) is the most tremendous object in the Solar system. Its mass is 99.8% of the total mass of the Solar system, and the mass of Jupiter is almost everything else. At the moment the mass of the Sun consists of 70% hydrogen and 28% helium. All other components (metals) are less than 2%. The interest rates are very slowly changing as the Sun converts hydrogen into helium in its core. The conditions in the core of the Sun, which is about 25% of the radius of the star are extreme. The temperature is 15.6 million degrees Kelvin and the pressure is 250 billion atmospheres. The power of the Sun is 386 billion megawatts is provided by nuclear fusion reactions. Every second about 700.000.000 tons of hydrogen is converted into helium 695.000.000 and tons to 5,000,000 tons of energy in the form of gamma rays.

8. Solar system

Our Solar system consists of the Central star (the Sun) and nine planets: mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto, as well as numerous moons, millions of rocky asteroids and billions of icy comets.

7. VY Canis major (VY CMa)

The biggest star in the Universe (3 billion kilometers in diameter)

The star VY Canis major (VY Canis Majoris) is the largest and one of the brightest stars known at the moment. It is a red hypergiant in the constellation Canis major. Its radius greater than the radius of the Sun at 1800-2200 times, and a diameter of 3 billion kilometers. If she was placed in our Solar system, its surface would stretch beyond the orbit of Saturn. Some astronomers do not agree with this statement and believe that the star VY Canis major is actually much smaller, only 600 times greater than the Sun, and would stretch only to the orbit of Mars.

6. The largest amount of water ever discovered

Astronomers have discovered the largest and oldest mass of water ever detected in the Universe. A giant cloud of age at 12 billion years carries 140 trillion times more water than all the oceans of the Earth combined. The cloud of water vapor surrounds a supermassive black hole called a quasar located 12 billion light years from Earth. According to scientists, this discovery proved that water prevailed in the Universe throughout its existence.

5. Extremely huge supermassive black holes

(21 billion times the mass of the Sun)

Supermassive black hole is the largest type of black holes in the galaxy, ranging in size from hundreds of thousands to billions of solar masses. It is believed that most, and perhaps all galaxies, including the milky Way, contain supermassive Central black hole. One of these newly discovered monsters, weighing 21 billion times the mass of the Sun is a maelstrom of stars ovate. It is known as NGC 4889 is the brightest galaxy in a sprawling cloud of thousands of galaxies. This cloud is 336 million light-years away in the constellation of Berenices (Coma Berenices). This black hole is so large that our entire Solar system would fit in there about a dozen times.

4. The Milky Way

100.000-120.000 light years in diameter

The milky Way is a closed spiral galaxy with a diameter of about 100.000-120.000 light-years and containing 200-400 billion stars. It may contain at least as many planets, 10 billion of which can rotate in orbit in the habitable zone of their stars-parents.

3. El Gordo “El Gordo”

The biggest galaxy cluster (2×1015 Sun masses)

El Gordo is at a distance of more than 7 billion light-years from Earth, which means that watching him since birth. According to scientists involved in the study of this issue, this cluster of galaxies is the most massive, hot and emit more x-rays than any other known cluster at this distance or even further.

Central galaxy in the middle of El Gordo is unusually bright and has the amazing blue rays in the optical wavelengths. The authors suggest that this extreme galaxy resulted from a collision and merger of two galaxies in the center of each cluster.

Using data from the space telescope Spitzer (Spitzer) and optical images, it was estimated that about 1% of the total mass of the cluster is a star, while all the rest is hot gas, filling the spaces between the stars and the visible telescope Chandra (Chandra). A similar proportion of gas and stars corresponds with the results from other massive clusters.

The estimated size is 156 billion light years

A picture is worth a thousand words, so look at this stretched out and try to imagine/understand how big our universe is. Prodigious figures are given below. Here is the link to the full-size picture .

Earth 1.27×104 km

The sun is 1.39×106 km

Solar System 2.99×1010 km or 0,0032 light years

Space solar interstellar 6.17×1014 km or 65 light-years

The milky Way 1.51×1018 km or 160,.00 light years

Local Supercluster 1.2×1021 km or 130 million light years
