Can Orion only be seen in winter? What about spring, summer and autumn?

Orion is a very huge constellation located in the equatorial belt and has always been the observation object of astronomy enthusiasts.

Immersed in the long galaxy, with the change of observation season, it is sometimes clearly visible and sometimes hidden in the starry sky.

So, Orion can only be seen in winter? What about other seasons? Let's get to know each other.

The best observation date of Orion is1from early February to early April. It rises from the southeast when it appears, and falls from the southwest after crossing the zenith. The alpha and beta stars of Orion are very bright and easy to see in the cloudless night sky. However, because there are many bright stars in the winter night sky, other stars are needed to identify the whole picture of Orion.

Usually, people use Orion's belt Samsung arranged in a straight line as a distinguishing sign for finding Orion. The brightness of these three stars is between 1.7 and 2.3, which can be clearly seen in the sky with little light damage. The alpha star and the beta star are located at the north and south ends of the vertical line in the middle of the belt. After people find these two stars, they can find G and κ stars in the west of α star and in the east of β star, so the whole outline of Orion will be vividly portrayed.

In addition to winter, people can also observe Orion in the northern hemisphere in spring and autumn, but it is difficult to see it in the northern hemisphere in summer. This is because in summer, Orion and the sun are in a straight line with the earth, but the sun is in the middle. Orion is obscured by the sun, and it is difficult for people to see it. In this season, from the latitude and longitude, Orion can only be seen from above and below the equator.

Bian Xiao summed up the area of 30 degrees north latitude here. 1 From early February to early April, at 2 1 at different times, the orientation of Orion can be observed: 65438+February1,2 1: 00, 20-45, east-southeast; 65438+1 October1,2 1: 00, 45-70, southeast of zenith; February 1, 2 1: 00, 60-90, south of zenith; March 1, 2 1: 00, 40-65, west-southwest; April 1, 20: 00, 30-55, West.

Conclusion: The best observation time of Orion is autumn and winter. The star itself does not emit light, and the sun shines on the surface of the star, so different irradiation points or different latitudes and longitudes will have an impact on star observation.
