The long, long journey has ended…

Dale Rutter / NASA

About six million years ago, a small comet, which we now know as Comet Elenin, under the influence gravitational perturbations unknown to us, strayed out of its orbit and went on to its first, and as we now know, last encounter with the Sun. During its long journey, man appeared on the Earth, who, in the early 21st century, made his way so as to discover a distant wanderer…

Comet C/2010 X1 (Elenin) was discovered a year ago, December 10, 2010. At that time nothing predicted the “fame” attained by this comet, informally known as the “Great Doomsday Comet of 2011”. It is still unclear why this comet was selected for this role, but it happened that its influence was supposed to be responsible for a shift in Earth’s magnetic poles, terrible earthquakes, and, simply, a collision with the Earth. Other charlatans said that alien spacecraft were flying behind it, and its occupants would soon take over the Earth … As we can see now, when the comet, not having caused anyone harm, became interplanetary dust; nothing of the sort happened.

The whole story was another example of the pressure of hysteria, intimidating people, and just making money. So it was in 1997 with Comet Hale-Bopp, so it was with Comet Elenin. I hope that in the future, the number of people believing in all the lies written about Comet C/2010 X1 will lessen. But unfortunately, it is clear that such stories will be repeated in just a few years as the wheel of history turns. But the real truth and science will prevail again!

The cloud of fragments remaining from comet Elenin has been detected

After many attempts to find any remains of Comet Elenin, they have been located. The first message came from Ernesto Guido, Giovanni Sostero, and Nick Howes. On their images, a small extended cloud with low surface brightness was visible. This cloud is easily seen on Ronald Ligustri’s image which can be seen at left. During the night of October 21-22 at our observatory we also made followup observations of the comet, and the motion of the cloud was confirmed. You can see the animation here. The Moon is leaving, and the comet is climbing higher in the northern sky. I think, in the near future new images will be obtained of this object, once known as Comet Elenin.

Turned to dust

As we know, the first signs of the breakup of the comet were noted in the middle of August by the Australian amateur astronomer Michael Mattiazzo. With each passing day the pseudo-nucleus of the comet became more diffuse and less bright. Michael observed the comet right up to its perihelion and for several days afterwards. It became apparent that the comet was irreparably breaking up, but the question remained – would we see anything on the SOHO images?

SOHO could not see the comet; neither could northern hemisphere observers, where the comet was due to become visible beginning the second week of October. I made one of the first attempts to find the comet on October 6th when it was still very low on the horizon. These observations were made during navigational twilight. I could not say for sure that I had detected the comet, although combining all the images showed a possible object. However, because motion could not be confirmed, we cannot say this was actually the comet.

The second attempt took place three days later, on October 9th. Down to magnitude 19.7, Comet Elenin was not visible in a field of view of 100 x 100 minutes of arc. The next day Ernesto Guido, Giovanni Sostero, and Nick Howes, using the 2-meter Faulkes telescope also got negative results. Their second attempt on October 17th, one day after closest approach of the comet to the Earth, also had negative results – the remains of the comet were not found.

At the moment there is not one confirmed sighting of the comet. Possibly, searches for what remains of the comet will be carried out by more powerful instruments in a few days when they can observe it without the Moon. But one can already say with certainty that the comet has turned to dust…

Comet Elenin disintegrated

Based on the first images of the comet Elenin after its exit from the conjunction with the Sun, we can tell what comet mostly disintegrated. Maybe we can still observe  swarm of comet’s debris. On the left you can see possible position of this “cloud”. Brightness of this object does not exceed 18m, which means what now, magnitude of the comet is lower then predicted on 12m. Hopefully in the near future debris of the comet will be observed on a large telescopes, and perhaps we’ll see some details of this “cloud”. Currently the comet is very low above the horizon and I observed it in nautical twilight, but comet will quickly ascend on the Northern skies, but it’s further observations may be hampered by the full Moon….

Real facts about comet Elenin

  1. At this moment the comet disintegrated into a large number of small fragments, which we may be able to see with the large telescope at the early October;
  2. The fragments of the comet did not change it path and will be flying by orbit of the comet, i.e., not will come to the Earth closer than 35 000 000 km;
  3. Currently the comet Elenin is not visible on the images from the SOHO and STEREO spacecrafts;
  4. Comet visible on images from the spacecraft STEREO-B (HI-1 camera) is comet 45P / (Honda-Mrkos-Pajdusakova);
  5. Comet Elenin, even if not disintegrated, do not eclipse the Sun, the density of a comet’s gas envelopes (coma) is negligible and earthly observer would not have noticed this event;
  6. The Earth will not pass through the tail of the comet, because at now it does not exist;
  7. The comet will not cause and couldn’t do any harm to us and our planet.
