When and where will there be comets in 2012, or asteroids like meteors

The next copy is the Lyrid meteor shower.

Lyra Attack. Meteor shower, around April 22.

It's a pity that this day happens to be farming.

On the twentieth day of the calendar, the moon rises from the east in the second half of the night, and the radiant Lyra rises from the east at 10 o'clock, and the amount of meteors may be greatly reduced due to the influence of the moonlight in the early morning.

Hope it helps.

According to Kou Wen, an astronomical expert at the Beijing Planetarium, there will be four partial solar eclipses and two total lunar eclipses in 2011, with the four partial solar eclipses being January.

A partial solar eclipse that can be seen in the western part of China at sunset on the afternoon of the 4th; It was a day that could be seen in the northeastern part of our country at sunrise in the early morning of June 2.

Partial eclipse; The two partial solar eclipses on July 1 and November 25 occurred in the Antarctic region and were not visible in China.

In addition, there will be two total lunar eclipses in 2011: one on June 16, when the Moon enters the Earth's umbra at 2:22 a.m.

The total eclipse will not end until the moon falls below the horizon, and there will be a scene of eclipse and falling; Another time was on the night of December 10, that night.

At 20:45, the moon enters the earth's umbra and leaves the earth's umbra at 0:18 the next morning.

There are meteor showers every month.

According to Cowen, one or two meteor swarms will visit Earth almost every month next year, so strictly speaking, meteor showers are not uncommon, but.

Some meteor showers are still worth looking forward to because of their high flow and good observation results.

On January 4, the Quadrantids are extremely large, with a theoretical maximum of 120, and the moon phase that night is a new moon, which is very worth looking forward to, but the meteor shower's.

The maximum occurred at about 8 a.m. on the same day, and it is recommended to observe it in the early morning of the same day. In addition, the Perseid meteor shower is extremely large on August 13 and the lion on November 18.

The Considids are extremely large and the Geminid meteor shower is extremely large on December 14, and it is possible to enjoy the meteor shower at these times.

There are many opportunities to observe planets.

"Great elongation" is a phenomenon unique to planets on Earth, and Mercury and Venus are often submerged due to their proximity to the Sun.

In the bright sunshine, and the "great elongation" is a good opportunity to observe the two planets. Mercury in 2011 will appear at 7 major elongations.

The best measurements are for the western elongation on May 8 and the eastern elongation on July 20, and it will be very easy to see the east before sunrise and the west after sunset.

to the planet closest to the Sun. The only major elongation of Venus in 2011 occurred on January 8, when it was in the eastern sky before dawn.

See this bright planet in the air.

The best time to observe extraterrestrial planets is around their "opposition," which is when the extraterrestrial planet moves up to 180 degrees from the ecliptic longitude of the Sun.

At this time, they are also close to the Earth, and their brightness is relatively bright, which is suitable for observation. In 2011, Saturn and Jupiter will be at opposition in April.

On the 4th and 29th of October, Saturn is likely to be more visible than Jupiter, and can be seen clearly through a small telescope.

Detect Saturn's rings; Jupiter's highlight is its four Galilean moons, whose positions can be seen through ordinary astronomical telescopes for a short period of time.

Jupiter's Great Red Spot requires a larger aperture telescope to see. In 2011, other planetary oppositions include:

Uranus at opposition on September 26 and Neptune on August 23.

April 22, 2012, the evening of the Lyrid meteor shower.

It can be seen from the evening of the 22nd to the next day, the number of meteors is more than 100 per hour, and the radiant Lyra is visible in the east at about 10 pm on the 22nd, which can assist the bright star of Lyra to distinguish, Vega, which is the fifth brightest star on the earth in addition to the sun, and it is also more conspicuous. And at this time, the moon has set in the west, which is also a very important condition for conjugation, without the interference of moonlight, which is of great value for appreciating meteor showers. There is also the landlord do not think that the meteor shower is like the rain seen on TV, called a meteor shower, meteor storm refers to the occurrence of more than 1000 meteors per hour, the most recent meteor shower in 2001 Leonid meteor shower, so this meteor shower is difficult to wait.

What we usually say is more common, generally a dozen or more than a hundred pieces per hour.

No, the return of a comet is not very easy to come with once, sometimes not once for several generations.

If a comet, which is a threat to Earth, returns, do you think countries will report it?

If the comet the landlord is talking about is ISON, I'm sorry, it disintegrated after perihelion, leaving only a small piece of debris. Isn't it very abstract, to put it bluntly, the brightness has dropped greatly, and the brightness this morning has dropped to 8 levels, and the city is completely hopeless to the naked eye. Once you know this concept, you can ask the next four questions:

It is impossible with the naked eye, and it can be challenging to observe with small telescopes.

After passing perihelion, ISON moves rapidly towards the north celestial pole, located in the constellation Hercules in mid-December, and appears in the northwest sky after sunset, so it is a dusk star, and it cannot be observed in the early morning unless it reaches the constant display circle of Draco.

After sunset lies in the northwest sky.

If you look at it over a longer period of time, you can see the comet's position changing in the sky. For example, in mid-November, ison is located in the constellation Virgo, and a month later it reaches the constellation Hercules, moving a distance of about 60-70°. However, during overnight observations, such a change in smile was difficult to detect with the naked eye.

Of course, because the rotation of the earth causes the movement of the celestial bodies on Sunday, like the sun rising in the east and setting in the west, all celestial bodies will do the same.

In fact, there is not only one comet in the sky, but also two comets that have reached a magnitude of 6 or more. Personally, I think that such a bright comet is more embarrassing, and it is not too difficult to find it, but the observation is average, unless there is a strong interest, it is difficult to attract the attention of the public.

The Perseid meteor shower on the night of August 12-13, 2012 has passed, so let's say that it is worth the best meteor shower in the future. (Of course, if you are in a place with little light damage, you can see a few meteors on a moonless sunny night, and there are more occasional meteors in autumn and winter).

This year, let's look forward to the Draconid meteor shower on October 8, the return of the parent comet 21p, and there may be an outbreak (uncertain).

On October 21 of this year, the Orionid meteor shower is extremely large, zhr = 25 hours (not every minute) in large cities and urban areas.

On November 17 this year, the Leonid meteor shower is extremely large, and although the observation is completely undisturbed by the moonlight, the flow is very small, zhr = 15 hours, and there is no need to see it in large cities and urban areas.

The Geminid meteor shower on the night of December 13-14 this year is extremely large (the observation is not disturbed by moonlight) zhr = 120 hours, which is worth ** Just be well prepared, especially from the cold.

Observation conditions] Generally speaking, considering the serious light damage in large cities, if you want to see meteor showers, the Geminid meteor shower on December 13 and the Perseid meteor shower on August 12 are the most recommended (the meteor showers we are familiar with are both periodic meteor showers, which occur every year). Even for these 2 major meteor showers, the farther away from the urban area is the better, and novices are likely to not see or only see a few in the urban area. Of course, other small cities should avoid city lights appropriately depending on the serious situation of light damage.

In short, you have to go to a place where you can see a lot of stars, and it is best for novices to go to a place where you can see dense stars.

You can ask, I'll check the specific ** time for you.

April 22, 2012, the evening of the Lyrid meteor shower. But unfortunately, it's scary until next year

What about a single meteor**? Generally, there are only ** meteor showers and comets, which will be reported on TV in advance.

The three major meteor showers in October, astronomer Wang Sishen recently revealed the news that there are three meteor showers coming in October this year. The three meteor showers come from the constellations Draco, Southern Taurus, and Orion, and the fastest one will come on October 9.

9th. The Draconids are extremely large.

In 1933 and 1946, the Celestial Dragon Sunxiaoqi meteor shower had eruptions of thousands or even tens of thousands per hour. According to Kou Wen, an expert from the Beijing Planetarium, although there are still many uncertainties in the forecast of the Draconid meteor shower, many astronomers from all over the world ** This year's Draconid meteor shower is mainly concentrated in the period from October 8th to 9th, Beijing time, and the best observation time is around 4 am on October 9th, when the Draconid meteor shower may erupt about 200 pieces per hour.

October 9 this year coincides with the thirteenth day of the lunar calendar, and the interference of the waxing gibbous moon on the observation is unavoidable, but fortunately, the moon will set at around 2 o'clock on the same day, and the interference of light pollution will be reduced. The radiant of the Draconid meteor shower is located at the head of the dragon, and for areas north of 40 degrees north latitude, the dragon's head will never fall below the horizon, which is also a great advantage for observing the meteor shower.

10th. The Southern Taurids are extremely large.

According to the forecast of the International Meteor Organization, the Southern Taurids will be active from September 10 this year and will continue until November 20, with a high probability of October 10. At this time, the radiant of the meteor shower is still at a definite distance from the constellation Taurus, which is located in the celestial region of the constellation Pisces. One of the main features of this meteor shower is that the velocity of meteoroids is only 27 kilometers per second, and most meteors in this group appear to be relatively slow, so it is not difficult to distinguish them from other groups.

21st. The Orionid meteor shower is extremely large.

As one of the two meteor showers brought to us by Halley's Comet every year, the Orionid meteor shower has a relatively stable flow and is the most noteworthy meteor shower in October every year. The Orionid meteor shower is active throughout October and early November. According to the forecast given by the International Meteor Organization, the meteor shower will appear on October 21 this year, and the Orionid meteor shower can reach a meteoroid speed of 66 kilometers per second, which is a fast meteor.

The Orionid meteor shower's radiant is located between the bright stars Betelgeuse and Gemini, and is characterized by a large and gentle radiant that may last for 1 day or even longer, and is worth observing if the weather is fine.

Do you remember the last time the meteor shower was promised?
