Mysterious Comet C / 2015 D1 survived after a meeting with the Sun - VIDEO PDF Print E-mail

SOHO observatory to monitor the Sun photographed unusual comet, surviving after flying dangerously close to the star. "Meeting» C / 2015 D1 with luminary was recorded in the period from 18 to 21 of this month. The uniqueness of this comet is that it does not belong to any known family of comets.

Most comets photographed by a spacecraft Solar and Heliospheric Observatory (SOHO), belong to the family Sungrazing comet Kreutz, who are believed to be part of one giant comet that was destroyed centuries ago. According to this theory, the majority of "Sungrazers" moving along trajectories near the surface of the Sun, are fragments of shattered comet with a diameter of 20 to 100 kilometers. During its rotation around the Sun for about 800 years, most of the comet and destroyed more than once.

According to some estimates, the comet near the Sun do not exceed ten meters in diameter. For comparison, the diameter of the Sun is 1,390,000 kilometers.



Scientists also surprised that C / 2015 D1 passed from the surface of the Sun at a distance of about 3.5 million kilometers. Most comets evaporate under the influence of strong Sunlight, because they consist of ice and mud. The researchers also noted an unusual brightness of C / 2015 D1.

There is a big chance that in the coming weeks, the comet will be visible from Earth. But it is also possible that the events on the Sun rather quickly lead to her death - said scientists from the Naval Research Laboratory in Washington.

Apparatus SOHO was launched in 1995. During his tenure, he discovered a large number of comets. Recent discoveries including its general list of discoveries at number 2875.

Sungrazing comet single meet several times a year. But so far none of the devices for observing the Sun due to insufficient sensitivity of onboard instruments are not able to capture the comet in such close proximity to the Sun.

In 2012, with the help of telescopes SDO (Solar Dynamics Observatory), SOHO and STEREO (Solar-Terrestrial Relations Observatory), scientists were able to trace the flight of a comet C / 2011 N3 of the Kreutz family to destruction at a distance of 100,000 kilometers from the Sun's surface.

A recent probe Philae landing on the comet 67P / Churyumov - Gerasimenko comet for the first time allowed to study as close as possible to it from a distance. Analysis of water samples from the comet 67P / Churyumov - Gerasimenko showed that its chemical composition is different from Earth's. This refutes the suggestion of some scholars that the water was brought to the Earth from space.
