It is possible to distinguish the total solar eclipse in August from a set of bright astronomical events of 2017. Besides, such phenomena as flight of an ice comet in February, bright Geminida in December, and also emergence in a firmament of especially larger and bright Mercury and Jupiter at the beginning of a year will be available to observers.
1. A comet 45P / Honda — Mrkosa — Paydushakova, on February 11
In the first half of February the firmament will light up flight of a comet. After it rounded the Sun in December, 2016, the comet 45P / Honda — Mrkosa — Paydushakova begins return to external area of Solar system. Its emergence in a firmament can be observed at sunrise, it will fly by through constellations of Oryol and Hercules. On February 11 the comet will appear most close to Earth — apart about 12,4 million km. Scientists expect that its brightness will reach the level at which it can be observed with the naked eye.
2. Ring-shaped eclipse, on February 26
The happy observers who appeared on the way of a shadow in the Southern hemisphere will be able to see a ring-shaped solar eclipse or as it is called still, “fire ring”. It occurs when the disk of the Moon is too small to close the Sun therefore around a dark lunar silhouette it is possible to see a sunlight. The path of a shadow will pass through the southern part of the water area of the Pacific Ocean, will cross South America and will end in Africa. To the North and the South from it in many regions it will be possible to see a private solar eclipse.
3. Mercury, Mars and Moon, on March 29
After a decline observers should look at the western site of a firmament where the thin crescent moon forms an impressive celestial triangle with Mercury below and to the right of it, and also with Mars which will crown to steam. Uniqueness of an event is that Mercury will be in the highest point, and also will be very bright. It is difficult to observe this the planet, next to the Sun, as usually it is lost in gloss of a star. But at the end of March Mercury will reach the most distant point from a star for the terrestrial observer.
4. Moon and Jupiter, on April 10
Floodlight will make couple Speke — the brightest star in Virgo constellation, during the whole year. But in April the major planet of Solar system will meet the Moon. This night two celestial bodies together will ascend in the east right after sunset in the West. At this time Jupiter will look especially brightly as in only 3 weeks opposition of Jupiter and the Sun will take place before — when the planet is on continuation of the Sun Earth line.
5. The total solar eclipse, on August 21
This year residents of the USA, private phases — inhabitants of North America, Western Europe and South America will be able to observe the complete phase of an eclipse. It will be possible to see an eclipse in all territory of the USA from the coast to the coast, its path will pass from Oregon to South Carolina. The complete phase will be able to be observed in many cities, and the majority of the population of the country will be a maximum in 1 day of traveling from places where it will be possible to see this phenomenon. The partial eclipse will be available on the larger square on all continent.
6. Venus and Jupiter, on November 13
Two brightest celestial bodies will agree on our firmament at sunrise on November 13. Connection can be seen in the bottom of a palate in the east, two planets will divide only 18 angular minutes. As this event will take place low to the horizon, planets will be not so easy to be seen because of light of morning twilight therefore the field-glass will make viewing more pleasant.
7. Geminida, on December 13
The meteor shower of Geminida will reach peak this night. As a rule, during this meteoric rain it is possible to see 60-120 meteors an hour, but this year it will be the singular as light of the decreasing moon will interfere with observation only till midnight. As soon as the moon comes for the horizon, the best time for observation of meteors — pre-dawn clocks on December 14 when the stream just reaches peak will begin.
