Please set the alarm clock. In the middle of the night of July 22, the Eastern Night Sky can enjoy the Mars with the Month of Astronomical Landscape

The moon and Mars are close to each other

Soon after, the moon and Mars will complete a "close contact" in the sky -they will pass by the minimum spacing of only 58.3 angles (about 1 degree in the sky). At this time, the moon will be on the 22nd day after the new moon.

In Kunming, people can see the pair of double stars in the dawn sky. It raises at 01:22 in the summer of Canada, disappeared in the field of vision at 06:13, and reaches the height of 64 ° above the East Horizon.

The moon will be at -11.5 MAG; Mars's MAG is 0.3. Both celebrities are located in Aries.

The distance between them is too large to watch it in the visual field of the telescope, but it can be observed with naked eyes or binocular telescope.

At the same time, this pair will also share the same Red Scripture -called a combination point.

The angle separation diagram between the moon and Mars can be used here at the closest time.

At the closest moment, the position of the combination is as follows:

The coordinates above are given in J2000.0. This pair of double stars will be separated from the sun in Cancer at a 77 ° angle

Mars' Moon Covering Star Phenomenon

The moon will go through the front of Mars to form the phenomenon of the moon cover, and this phenomenon can be observed in some areas of East Asia and the United States.

On the surface of the earth, only a small part of the area can observe the phenomenon of the moon cover. Because the distance between the moon and the earth is far less than the distance between the other celestial bodies, the exact position of the moon in the air is different from the location of the observer on the earth. This is because the observation position will generate huge vision. There will be a huge difference between the lunar positions observed from the opposite side of the earth on the other side. The visual difference is as high as twice, and the straight line distance is about four times the diameter of the full moon.

This means that if the moon runs from a particular celestial body, the location of the celestial body observed on the side of the Earth's side will be two degrees as observed on the other side of the earth. Visual differences.

Kunming will not be able to observe the phenomenon of this month.

The following map shows the visibility of this month's hidden stars in the world. We use two different lines to mark the naked eye that Mars disappears (marked with red lines) and duplication (identified with blue line). The solid line indicates that the two phenomena may be observed through the two -tube telescope in the air. The dotted line indicates that these two phenomena will appear above the horizon marked area, but it may not be observed because the sky is too bright or the moon is close to the horizon.

The area outside the line states that in these places, the moon will not pass through the front of Mars, or the moon is located below the horizon when the moon covering the star phenomenon appears.

related information

Mars is the fourth far away from the sun, and the second small planet in the solar system, which is larger than Mercury. In English, Mars has the name of the Roman God of War. Mars is a planet with a thin atmosphere. Its crust is mainly composed of elements similar to the earth crust and the core of iron and nickel. The surface characteristics of Mars are impact pits, valleys, dunes and polar ice caps. It also has two small satellites with irregular shapes.

Some of the most significant surface features on Mars include Olympus and sailor valley. The former is the largest volcanic and highest peak known on the planet of the solar system, and the latter is one of the largest canyons on Mars. The smooth northern hemisphere is covered with 40 %of Mars, which may be a huge impact feature. [19] The day and seasons on Mars are similar to the earth, because its self -rotation cycle is similar to the tilt of the plane from the plane of the eclosity as the earth. The liquid water on the surface of Mars is impossible, because the pressure of the atmosphere is very low, and it is less than 1 %of the earth's atmospheric pressure.

The two polar ice caps of Mars seem to be composed of water. [22] [23] Several evidence shows that Mars is more humid in the distant past, so it may be more suitable for the existence of life. However, whether there has been life there and whether it can survive to this day is still a question of no answer.
