The green deer forest comet flies over Earth and is the brightest visible to the naked eye today.
Su Yi, chairman of the Tianjin Astronomical Society and professor of Nankai University, informed reporters on the 15th that a comet named "Lulin" has entered the best observation period. Around February 24, the comet will come into public view. If the weather is fine, it can be seen with the naked eye, with a magnitude of 4 to 5 stars, and it is the end of the lunar month, so there is no moonlight interference throughout the night.
Su Yi said that the comet "Deer Forest" will be located between Virgo and Leo, and with the bright and beautiful Saturn also gathering in it, it will be easy to find. With the help of a small astronomical telescope, you can enjoy the mysterious beauty of the tail comet "Deer Forest" and the ringed Saturn.
Comet Lulin is one of the three comets discovered by amateur astronomers in China in recent years. The comet was discovered on July 11, 2007 by Ye Quanzhi, an undergraduate student at Sun Yat-sen University in Guangzhou, and Lin Qisheng, an observation assistant at the Lulin Observatory of the Institute of Astronomy of ** University in Taiwan.
The International Astronomical Union then designated the comet C 2007N3 and named it "Lulin" after the name of the observatory that discovered it. Comet Lulin passed perihelion on January 10 this year and was closest to Earth on February 24, about 60 million kilometers.
According to astronomical experts, comets are small bodies in the solar system, and their main component is water ice. Most comets are faint and faint, bright enough to be seen with the naked eye.
Astronomical experts said that if they were lucky enough to witness the comet and enjoy the beautiful starry sky at the same time, it would undoubtedly be a surprise for the 2009 International Year of Astronomy.

Anonymous users2024-02-05Comet Lulin was the first comet discovered in Taiwan and the first in collaboration with the Chinese astronomical community. The comet was discovered on July 11, 2007 by Ye Quanzhi, an undergraduate student at Sun Yat-sen University in Guangzhou, and Lin Qisheng, an observation assistant at the Lulin Observatory of the Institute of Astronomy of ** University in Taiwan.
Comet Deerlin's atmosphere is as large as Jupiter's, and the gas that makes up the comet's atmosphere is the key to its green color. The air flow ejected from the comet's nucleus contains cyanide (a toxic gas found on many comets) and divalent carbon (C2). Both of these substances glow green when illuminated by sunlight in a vacuum environment near the comet.
In 1910, people panicked when astronomers said that Halley's Comet, which is rich in cyanide in the tail of the comet, would pass near the Earth. False alarm: The comet's slender tail does not penetrate the dense atmosphere that surrounds the Earth; Even if it penetrates the atmosphere, it doesn't contain enough cyanide to cause real trouble.
Comet Deerlin will cause less trouble than Halley's Comet. At the end of February 2009, when Comet Deer Grove is closest to Earth, it will be 38 million miles away from Earth and will be completely harmless to Earth. Around February 24, 2009, it is the closest to the Earth, about 60 million kilometers, with a magnitude of 4 to 5 stars, and if the weather is fine, it can be seen with the naked eye.

Anonymous users2024-02-03Comet Lulin was discovered by the International Astronomical Union (IAU) and named "C 2007N3 (Lulin)" in cooperation with the Undergraduate Observatory of Sun Yat-sen University in China. The new Chinese meaning of "c 2007n3" is: "the third confirmed comet, which is a non-periodic comet".
It is estimated that the comet passed perigee on February 20, 2009, only 100 million kilometers away from the Earth, and its brightness is magnitude, barely visible to the naked eye. Some of the information on the comet Deerlin** shows that the comet has a double tail and is green in color.
On our planet, there are generally no stars during the day, and that's because of the Earth's atmosphere. >>>More

There are many of them, and they generally occur in high latitudes, such as Alaska, Canada, Russia, Sweden, Finland, Norway, Iceland, Greenland, etc. In these areas, the Northern Lights are parked (exceptions are not excluded, such as China's Aurora in the Northeast, and even in Henan). And the occurrence area of the Southern Lights is the Antarctic continent, intelligence, Argentina, etc.
