The order of the planets

Not so long ago such a statement would cause an uproar in any self-respecting astrophysicist and most likely, it ended in the usual enumeration of the several variants of the origin of our Solar system. Today, however, a number of researchers not only did not reject this version and think its main. What is the reason? We will try to understand.

It all started with sightings NASA space Observatory named “Kepler”. The satellite was launched in 2009, and in 2020 due to the loss of orientation in space failed. The Observatory was equipped with incredibly sensitive Photometer and specially designed to search for exoplanets, i.e. planets outside our Solar system like Earth. The ability of the apparatus to observe more than 100,000 stars at the same time very quickly gave the opportunity for scientists to get incredible data about other Solar systems.

In early 2010 the Observatory was discovered planetary system Kepler-33. The star Kepler-33, located in the constellation of Cygnus, was bigger than our Sun, and planets revolving around it, was very close to the parent star. Continue reading

Planets of the Solar system

Jupiter thousands of years ago named after the king of Roman gods, and reigns among the nine planets of our Solar system, rivaling the Sun in its splendor. The largest planet is located far beyond the main asteroid belt. The mass of Jupiter exceeds the mass of all other planets combined.

Jupiter is the largest planet in the Solar system. The semimajor axis of Jupiter’s orbit is 5.2.e. the eccentricity of the orbit e = 0,0489, the period orbits – 11,867 years. The inclination of the orbital plane to the plane of the Ecliptic is 1°1817″. The average speed along the orbit – about 13.1 km/s.

The period of rotation around the axis is 9 hours and 55 minutes. Each dot on the equator moves at a speed of 45 thousand miles per hour. Due to the centrifugal force of Jupiter is noticeably flattened (compression rate greater than 6 %). Since Jupiter is not a solid ball, and consists of gas and liquid, the Equatorial parts rotate faster than the polar regions. The rotation axis of Jupiter is nearly perpendicular to its orbit, therefore, the planet has no seasons.

The mass of the planet is M = 318 M = 1,9∙10 27 kg, radius R = 11,2 R = 71 492 km, However, Jupiter is very thin: its density is 1.33 g/cm 3. which is four times less than the density of the Earth. The acceleration of gravity at the level of the cloud surface of Jupiter sostavljaet = 2,53 g. Continue reading

The origin of the solar system

The sun and the solar system was formed about 4.5 billion years ago. The solar system originated from a cloud, composed of gas and dust particles moving. Under the influence of its weight of it formed a disk in the center of which formed the Sun .

Gradually within the disk began to form solid materials. They faced each other, whereby a large celestial body. Their size corresponds to the existing planets. Inside the nebulae, where the temperature was high enough to form rocky planets. Far from the center formed the giant planets, they contain a large amount of ice, and they were surrounded by a thick layer of gas.

Within the Solar system the temperature even higher, and planets formed from rocky debris of the solar nebula. They are in contact with each other, forming a large celestial body. They attract each other by virtue of the power of the law of gravity and give birth to planets of terrestrial group. The atmosphere of the Earth and Venus, the largest among them, tight.

The atmosphere of Mars, a smaller planet is less dense, and mercury. the smallest planet of this group, it is very sparse compared to earth is not readily available. Continue reading
