The planet Saturn will be at opposition (directly opposite the Sun) at about 6.00 am GMT on Monday 2 August 2021. This means that it will both be at its closest to the Earth this year, about 8.9 AU (8.9 times the average distance between the Earth and the Sun, or about 1 331 000 000 km), and completely illuminated by the Sun. While it is not obvious to the naked eye observer, the planets have phases just like those of the Moon; being further from the Sun than the Earth, Saturn is 'full' when directly opposite the Sun.
While the relative positions of the planets have no direct influence on life on Earth, the opposition of Saturn does present the best opportunity for observations of the planet by Earth-based observers. On Monday 2 August 2021 Saturn will appear as a bright object in the constellation of Capricornus, rising at about 8.45 pm in the southeast in the Northern Hemisphere and the northeast in the Southern Hemisphere. Seen through a moderate sized telescope both the planet and its rings should be visible, with the rings tilted at an angle of 26°. The Moon can cause problems for potential observers, as its glare can hinder viewing of nearby objects, however, the opposition coincides with a waning crescent Moon this year, which means the amount of Lunar glare will be low, helping observations.
