Saturn, Mars, Venus, and Jupiter line up in a straight line in late April 2022 and can be observed with the naked eye.

According to the

National Astronomical Observatory of Japan, a rare astronomical event in which Saturn, Mars, Venus, and Jupiter line up in a straight line can be observed in the Northern Hemisphere from southeast to east in late April 2022.

According to the National Astronomical Observatory of Japan, Saturn, Mars, and Venus have been lining up in the dawn sky since early April 2022, and Jupiter will join this line from around April 17, and Saturn, Mars, Venus, and Jupiter will be added from the highest position. Are lined up almost in a straight line.

The planets are lined up in the eastern to southeastern sky, and the time is around 4 am. Each grade is about 1 mag for Saturn, about 1 mag for Mars, -4 mag for Venus, -2 mag for Jupiter, and is bright enough to be observed with the naked eye even at dawn. However, because Jupiter is found in a low position, it may be difficult to see depending on the surrounding terrain and buildings.

Furthermore, from April 25th to 28th, it is possible to observe how the moon approaches these planets. Saturn and Mars are difficult to see due to the light of the moon, but negative magnitude Venus and Jupiter appear to shine even near the moon, and it seems that they can be observed even after the sky is slightly white.

According to Science Alert, a science news site, there is also a very rare event in which all the planets of the solar system such as Mercury, Venus, Mars, Jupiter, Saturn, Uranus, and Neptune line up in a row in the night sky in late June 2022. It can be observed. However, the brightness of Uranus is very dark at 6th magnitude, and Neptune is 8th magnitude, which is almost impossible to observe with the naked eye, so it seems that a telescope or binoculars will be required to actually observe the planetary series.
