On October 30, Venus will usher in the eastern distance, that is, Venus is in the east of the Sun, and from the Earth, Venus and the Sun have the largest opening angle. Venus will then appear like a beacon in the low southwest sky.
On October 30, Venus traveled to the farthest point to the east of the Sun, the "East Distance" of Venus, about 47 degrees from the Sun. Although its height is low at sunset on this day, the brightness can reach -4.6, which is like a searchlight, which is worth seeing. The further south, the better the conditions for observing Venus. In Beijing, for example, Venus appears at sunset at a low altitude of about 18 degrees to the southwest and will sink into the horizon after 20 minutes. In Guangzhou, venus has a horizon altitude of about 30 degrees at sunset and doesn't set for about an hour and a half.
Note that Venus in the evening is not in the west, but near the southwest of the south, which is quite bright in the twilight, and looks half-moon in the astronomical telescope. After that, The height of Venus will gradually rise and its brightness will become brighter and brighter!
To the naked eye, Venus is just a very bright star, with a brightness of about -4.4 magnitudes, and no star in the sky can match its brightness. In astronomical telescopes, Venus will also present a different scene, if you use a telescope magnified by more than twenty or thirty times to point at Venus, you will be surprised to see that Venus at this time is actually a semi-circular shape, like a winding moon. But now Venus has an apparent diameter of only 25 arcseconds, and the moon's apparent diameter is more than 70 times larger.
On December 4, Venus will reach its brightest moment of the year, with a maximum brightness of -4.9. Ideal conditions at its brightest, even during the day when the sun is strong in the morning and afternoon, you may wish to look for it to see if you can find a trace of Venus in the sky.
