Astronomers have discovered a ninth planet on the outskirts of the Solar system

While it “calculated” on the computer

In 2006, the Solar system lost one of the nine planets — Pluto stripped of planet status due to negligible size. But the discovery of American scientists threatens to return the ninth planet in the system — found a new celestial body, claiming the title.

The staff of the California Institute of technology Michael brown and Konstantin Batygin has published a paper in the reputable scientific journal “Astronomical journal” about his study, in which they “discovered” a new planet in the Solar system.

Celestial body has a mass of 5-10 times larger than our planet, and is about 20 times farther from Earth than Neptune. Despite the fact that Neptune is the most distant planet, until it 4300 million kilometers. Accordingly, before “the ninth planet” – about 8600 million. The problem is that open planet. while no one was looking through a telescope, it was discovered through computer simulation. However, the accuracy of such simulations is very high today.

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
