Comets of the centuries

In the fall of 2020, after Amateur astronomers Vitaly Nevsky and Artem Novichonok first observed the comet ISON, astronomers had expected that she would become a “Great comet” − a rare visitor, perhaps the brightest comet of the twenty-first century.

Alas, severely battered during the close approach to the Sun in November of this year, ISON no longer promises such a bright future. To the naked eye from the Ground to see it would be impossible − but hopes not worth it to lose. Somewhere in the dark depths of space, probably unnoticed by anyone else is racing the comet, which will deserve the attention and present us with an unforgettable sight. This has always been the Large comets appear about once a decade, and every century one of them was especially bright.

Comet ISON

We will tell you about these “comets of the century”, since the sixteenth century. It is interesting that they flew as a rule, in the second half of your century, and has had an average of once every 97 years. Given this, we can calculate that if the comet of Ikeya-Seki (C/1965 S1) visited the Earth in 1965, following a visitor, you can wait until 2029.

However, to predict what particular impossible: a Big comet can appear quite unexpectedly, at almost any time. The message we may hear tomorrow.

The ashes of the discoverer of Pluto arrived on Pluto

Unlikely in 1930, when the world learned of the existence of Pluto, someone could believe that someday people will be able to find there their last resting place. However, this can happen very soon. NASA space ship with the remains of Clyde Tombaugh, discoverer of Pluto, had almost reached the destination. The journey of the ship lasts for more than 9 years. Soon NASA promises to publish the first pictures from the distant dwarf planet, the study of which may help answer many questions about the origin of the entire Solar system.

kosmicheskiy the NASA New Horizons spacecraft has begun to explore Pluto. The aircraft approached the icy dwarf so much that this week the staff of the American space Agency promise to show him the first Pictures. The input apparatus into the atmosphere of the dwarf planet is scheduled for July 2015.

Note that the distance to Pluto is 30 times more than from the earth to the Sun, and the spacecraft New Horizons was launched back in early 2006. On his way the machine New Horizons flew past Jupiter and Saturn, in the literal sense, rebounding from their orbits, which gave the ship a significant acceleration. Up to this point most distant mission was considered an American Kosmicheskaya flight of Voyager, which in 1980 had reached Saturn. 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
