Your first night with a telescope: what the planets look like
What a small telescope shows on each planet and how to pick the best time tonight: the moon, Jupiter's moons, Saturn's rings, Venus's phase and Mars.
See tonight's planets for your location
Start with the moon and Jupiter
The moon is the easiest target and shows craters along the line between light and dark. Jupiter shows a small disc with two dark cloud belts and up to four bright moons in a line beside it — they move from night to night.
Saturn's rings
Even a small telescope at 30–50× shows Saturn's rings as a distinct shape. The planet looks small, so use your highest useful magnification on a steady night.
Wait for altitude
Look when a planet is highest in the sky: you see through less air, so the view is sharper and steadier. The planner shows that time for each planet tonight.
Next oppositions: the best nights for a telescope
An outer planet looks biggest and brightest around its opposition, when Earth passes between it and the sun. Magnitude is brightness on the astronomers' scale — lower is brighter, and anything below about 6 can be seen without a telescope from a dark site. Mars is the one to time: at its opposition on 19 February 2027 it is 0.68 AU away and magnitude -1.2, and a few months either side it is much further away and its disc is much smaller in the eyepiece.
| Planet | Opposition (UTC) | Magnitude | Distance from Earth |
|---|---|---|---|
| Uranus | 25 November 2026 | +5.6 | 18.44 AU 2,759 million km |
| Jupiter | 11 February 2027 | -2.6 | 4.36 AU 652 million km |
| Mars | 19 February 2027 | -1.2 | 0.68 AU 102 million km |
| Neptune | 28 September 2027 | +7.8 | 28.87 AU 4,319 million km |
| Saturn | 18 October 2027 | -0.1 | 8.33 AU 1,246 million km |
1 AU (astronomical unit) is the average Earth–sun distance, 149.6 million km.
