The moon will "meet" with Uranus

Xinhua News Agency, Tianjin, September 13 (Reporter Zhou Runjian) Astronomical forecast shows that on September 15, the moon will "meet" and "shoulders" with Uranus, and staged the phenomenon of the moon to cover the King of Heaven. Astronomical popular science experts said that although my country cannot see the process of "covering", the interesting public can see the very close -to -month king star on the evening of the 14th to the morning of the 15th.

Because the diameter of the moon is far greater than the visual diameter of the planet (or star), and the lunar and the planet's running orbit in the sky is similar, during which it is around the earth, planets (or stars) often cover up the background, this, this, this, this, this A phenomenon is called the moon covering the star. The public can usually observe the monthly cover of Venus, Mars, Jupiter, Saturn, and the star Bi Suwu, Xuanyuan XIV, and Xin Su two. Because Uranus is far away from the sun and the brightness is low, the moon covering Uranus is not common.

Member of the Chinese Astronomical Society and a director of the Tianjin Astronomical Society Xiu Lipeng introduced that this month, the heavenly king star happened in the morning of Beijing time, and the "cover" area was in Europe, North Africa, West Asia and other places. However, on the evening of September 14th, the public in our country can enjoy the moon with the king of the month, and the King Star is not far from the bottom left of the moon; before the dawn on September 15th, the two will get closer until it is drowned by the brilliance of the sun.

In the order of the sun from near and far, Uranus is the seventh planet that runs around the sun in the solar system. Its biggest feature is that the rotation axis has a tilt of nearly 98 ° from the rotation surface, which is called a "lying" rotating planet.

As the moon is gradually approaching Uranus, the two that can be seen in all parts of my country will be different in recent distances. Taking the Beijing area as an example, Uranus and the moon are about 1.4 degrees in the latest time, that is, the diameter of almost 3 full moon vision. The later the west is bright, the closer to the two can be seen.

"The observation of the Month of the Month of the Month is not very difficult to observe, especially suitable for taking pictures. At that time, the brightness of Uranus will reach 5.7, and the limits of human eyes can see about 6 such as 6, which means that in places with excellent observation conditions, After Tianwang Xing rose to a certain height, you can vaguely see its "Fang Rong" with the naked eye. However, if you want to see the style of 'heaven ", it is best to use the small astronomical telescope." Xiu Lipeng said.

When will the public in our country have the opportunity to see the Yue King's Star? No need to wait too long, there is such a good opportunity on November 8 this year. "Monthly full food will occur on the same day, and the phenomenon of the moon covering heaven star will be staged at the same time when the center of the moon is the center of the moon. Xiu Lipeng said.
