What are some rare astronomical phenomena in 2009? On which day? Please, 3Q

Just look for it on the Internet... Also, what does it mean to be rare? Lunar eclipse? Meteor shower? It seems like a lot、、、

Trouble, thanks!

If the seven planets were to line up in 2012, it would be clear that the planets should be in the same or opposite constellations when observed on Earth.

Jupiter is in Taurus and Saturn is in Leo, and these two can be considered opposite; But what about Uranus and Neptune? Uranus is in Pisces, Neptune is in Capricorn, and the two are exactly separated from Jupiter and Saturn, not to mention the seven planets in a straight line, just the four planets outside the solar system have not been leveled. The inner solar system is complicated to discuss because of its rapid movement, but the four outer planets alone are enough to deny the claims advocated by doomsday theorists in 2012.

** below is the position of the planet on December 21, 2012, and there may be a slight error, but the error will not exceed 1 arc second. I can't tell that it's lined up.

And what if it's in a straight line? There was already a big cross in 1999 (which is still true), but what happened that year?

There are other arguments in 2012 in astronomy, but when it comes to its scientific nature, I really don't dare to compliment, and I can find a lot of questions by an ordinary astronomy enthusiast like me, please see my refutation in the answer below for details.

But now it seems that the arguments concocted by the advocates of the 2012 apocalypse theory are becoming more and more naïve.

That's true, but not the extinction of the human race.

1. The seven planets are connected in a line;

2. An asteroid may hit multiple planets;

3. The temperature will rise a lot;

4. Sunspot activity is active;

Brother, I'm really convinced! On December 21, the fifth age of the Mayan calendar, which lasted about 57,600,000 days, ended, and Picton, a Mayan elder of Guatemalan origin who was at odds with the end of the world, finally couldn't help but jump out and say: "There is no such thing at all!"

He even went so far as to say that the doomsday theory originated in the West and that the Mayans never had such ideas. As for the year 2012 mentioned by the Mayans, it should refer to the awakening and transformation of human beings in terms of spirit and consciousness, so as to enter a new civilization.

P.S. 2012 Astronomical Phenomena.

January 31 – 433 Eros, the second-largest near-Earth asteroid (NEA), passes by about the distance of Earth.

March 18 – Mercury exploration satellite Courier is expected to enter Mercury's orbit.

May 21 – Annular solar eclipse, visible in southern China, Taiwan, southern Japan.

June 6 – Transit of Venus.

September 22 – during which a solar storm is possible (not devastating) and November 13 – a total solar eclipse will be visible in northern Australia and the South Pacific.

November 28 – a partial lunar eclipse. (Visible in China).

P.S. 2: Seven Stars Converge?

The most recent "planetary alignment" in history occurred at 0:00 on May 20, 2000, at an angle of 12 6 degrees. At this time, Mercury, Venus, Earth, Mars, Jupiter, Pluto, these seven planets are arranged in the range of degrees, the last "seven star alignment" occurred on March 6, 1965 at 9 o'clock, Mercury, Venus, Earth, Mars, Saturn, Uranus, Pluto are arranged in the range of 9 3 degrees. What will happen at 4 o'clock on December 6, 2149 will be the "Eight-Star Alignment", and the remaining 16 times will be the "Seven-Star Alignment".

On May 20, 2000, such a "planetary alignment" is a once-in-30-year event, which is rare in a person's lifetime, but it is frequent and not uncommon from the perspective of the large scale of time. However, the more superstitious belief among the people is that the appearance of the seven stars is a good omen.

So you better study hard. Don't think about 2012 anymore.

Don't think about it, you can't stop it from dying.

Mao, this is impossible, just a natural, phenomenon.

Brother was really defeated by you. Do you think there is a phenomenon of seven stars converging in astronomy now? If there is one. Bhabhi is really looking forward to crossing La. Wow! Ha! Ha!

There were no special astronomical phenomena in 2012. Some of them are ordinary astronomical phenomena.

For example, the solar eclipse (2-4 times a year): the annular solar eclipse on May 21, 2012 can be observed in the south of Luxiang China.

Lunar eclipses (0-2 times a year, with a probability of 0 less than 10%): a partial lunar eclipse.

Meteor showers (there are hundreds of meteor showers every year): Perseus, Gemini, Quadrant, Orion, Lyra and other meteor showers are worth paying attention to.

The celestial bodies in the solar system are never peaceful with all kinds of conjunctions, oppositions, and great elongations:

Mercury has 7-8 major elongations a year, and Venus has a major elongation once a year. Fire, wood, and earth clash with the sun every year.

But there is a once-in-a-century celestial phenomenon, if we miss the banquet, we probably won't have the opportunity to see it in our lifetime.

That is the transit of Venus on June 6, 2012, which is a once-in-a-century sight, so don't miss it.

There are also unpredictable celestial phenomena, such as supernova explosions and the appearance of large comets, which are completely unavoidable.

Some people on the Internet have advocated that the seven planets of the solar system will line up in a straight line in 2012, which can be ignored. Now there are some advocates of the 2012 apocalypse theory who are getting more and more clumsy, and they will only make things up in front of the computer, saying things that are out of tune and easy to refute, such as the change of the yellow and red corners.

The skies of 2012 are wonderful, they are abundant, but they are also normal.

I will only enumerate the more important astronomical phenomena!

This is the most important celestial event of 2012! The last time was June 8, 2004, and if you don't see it this time, the next time you will have it on December 10, 2117.

Note: The transit of Mercury occurs in the middle of the night and cannot be observed in Chinese mainland.
