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.

Flight to Mars, flight to Mars how far is Mars how to fly to Mars, mission duration to Mars
The planet Mars is one of the brightest objects in the night sky. Like a bright red star, it is visible to the naked eye in the night sky. Approximately every two years, Mars and Earth reach their closest point, called “opposition”. At this point, the distance between Mars and Earth is about 55 million kilometers. Almost every two years, the scientists take this opportunity to send to the red planet spacecraft. So how long does it take the spacecraft to reach Mars?
The total time of flight from Earth to Mars varies from 150 to 300 days, depending on the speed of launch, the position of the planets, the route and the amount of fuel on Board.
The first spacecraft to reach Mars was Mariner 4. The device was launched on 28 November 1964. On Mars he arrived on 14 July 1965, where he successfully made a series of 21 Photos. Continue reading
Equatorial diameter of Jupiter 142600 km (11 times the diameter of the earth). The period of rotation of Jupiter is the shortest of all the planets – 9h. 50min. 30C. at the equator and
9h. 55min. 40C. in the mid-latitudes. Because of the rapid rotation of this planet has strong compression at the poles. The mass of Jupiter is equal to
318 the mass of the Earth. The rotation axis of Jupiter is almost perpendicular
to the plane of its orbit (inclination of 87 degrees). The visible surface of Jupiter is an upper level clouds surrounding the planet.
Due to this, Jupiter has a relatively high albedo(0.45 m),and the details on its surface are constantly changing their appearance. From sustainable parts known Great Red spot, observed more than 300 years.
It is a huge oval formation size 35000 km in longitude and in latitude 14000 km
between the southern tropical and southern temperate bands. Color it reddish, not subject to change. Continue reading
