How to find planets in the night sky
Five planets are easy to see with the naked eye. Here is where to look, when, and how to recognise them.
Planets are among the easiest things to find in the night sky, because they are brighter than almost all stars. You need no equipment, only to know where and when to look.
Five planets you can see with your eyes
Mercury, Venus, Mars, Jupiter and Saturn are visible to the naked eye. Uranus is at the limit of naked-eye visibility and needs a very dark sky and a precise position. Neptune is always too faint and needs binoculars or a telescope.
How bright they get, calculated with Astronomy Engine for 2026 to 2035 (lower numbers are brighter, see magnitude):
| Planet | Brightest | Faintest (when visible at night) |
|---|---|---|
| Venus | −4.9 | −3.8 |
| Jupiter | −2.9 | −1.7 |
| Mars | −2.8 | +1.8 |
| Saturn | −0.6 | +1.0 |
For comparison, Sirius, the brightest star of the night sky, has magnitude −1.44 in the HYG star catalogue. When Venus or Jupiter are up, they are the brightest points of light in the sky apart from the Moon.
Where to look
The planets orbit the Sun in nearly the same plane, so from Earth they always appear close to the ecliptic, the path the Sun takes through the constellations of the zodiac during the year. In practice that means: look along the arc the Sun and the Moon follow across your sky. You will not find a planet near the celestial pole.
Mercury and Venus are inferior planets: their orbits are inside Earth’s, so they never appear far from the Sun. Mercury gets at most about 28° from the Sun and Venus about 47° (the range for 2026 to 2035 is 17.9° to 27.8° for Mercury and 45.4° to 47.2° for Venus). You see them low in the west after sunset or low in the east before sunrise, never in the middle of the night.
Mars, Jupiter and Saturn are superior planets and can be seen at any hour of the night. They are best around opposition, when Earth passes between them and the Sun: they are then up all night and at their brightest.
When a planet counts as visible
On Astrotempo a planet is listed as visible when it is at least 10° above your horizon while the Sun is at least 6° below it (the end of civil twilight, see twilight). Planets brighter than magnitude 5 are marked as visible to the eye, and fainter ones are marked as needing optics. The best time shown is when the planet is highest during that dark window.
How to tell a planet from a star
- Position: a bright “star” near the ecliptic that is not on a star chart is almost always a planet. The 3D sky view labels every planet for your place and time.
- It moves: over days and weeks, planets drift against the background stars.
- Binoculars: even small binoculars show Jupiter’s four large moons as points of light in a line, and a telescope shows Venus’s phase and Saturn’s rings.

Frequently asked questions
Which planets can I see without a telescope?
Mercury, Venus, Mars, Jupiter and Saturn. Uranus is at the limit of what the eye can see under a very dark sky, and Neptune always needs binoculars or a telescope.
Why can I only see Venus and Mercury in the evening or morning?
Their orbits are inside Earth's, so from here they never get far from the Sun: about 28° at most for Mercury and about 47° for Venus. They are only visible in twilight, after sunset or before sunrise.
