Opposition Feb 11, 2027 · magnitude −2.6 · up all night · disc ~44″ · in Leo · best Jan–Mar.
Once a year Jupiter lines up opposite the Sun, rising at sunset and blazing all night. In 2027 that night is February 11, when the giant planet shines at magnitude −2.6 — the brightest point in the night sky apart from the Moon and Venus — in the constellation Leo. There's a bonus this year: Mars reaches its own opposition just eight days later, a short hop away in the same constellation — two bright planets up all night together.
When and where to look
At opposition Jupiter rises in the east at sunset, is highest around local midnight, and sets at dawn — so any clear evening from late January through March works, sharpest when it's high near midnight. It's the brightest star-like object in that part of the sky, a steady creamy-white (planets don't twinkle), drifting through Leo not far from the bright star Regulus.
What you'll see
| Through… | What you'll see |
|---|---|
| Naked eye | A brilliant creamy-white 'star', brighter than anything in the night sky except the Moon and Venus, shining with a steady light rather than a twinkle. |
| Binoculars (10×50) | The four big Galilean moons — Io, Europa, Ganymede, Callisto — as tiny points strung either side of the planet, their arrangement visibly different night to night. |
| Small telescope (70–90mm) | Two dark cloud belts as stripes across a pale disc, plus the four moons — essentially the view that made Galileo famous. |
| 6-inch+ telescope | More belts and swirling festoons, the shadows of moons crossing the disc, and the Great Red Spot when it's turned our way. |
Two planets at opposition in Leo
2027 is a fine winter for planet-watchers: Jupiter and Mars reach opposition just over a week apart, both in Leo and both up all night. Jupiter is the brilliant white one; Mars, at opposition on February 19, is the fainter ruddy-orange one nearby. Catch them on the same night.
What to look through
A planet at opposition rewards optics — even a small telescope transforms the view.
- A small telescope (70–100mm refractor or 100mm+ reflector) — Jupiter's belts and moons; Saturn's rings
- Steady 10×50 binoculars on a tripod — shows Jupiter's four bright moons
- A 6-inch (150mm) or larger scope — cloud detail, the Great Red Spot, faint Mars markings
- A red-light headlamp and a star app — find your way without killing night vision
Frequently asked
When is Jupiter at opposition in 2027?
February 11, 2027. At opposition Jupiter is opposite the Sun, so it rises at sunset, is highest near midnight, and stays up all night — its brightest and closest showing of the year at magnitude −2.6.
What can I see on Jupiter with a small telescope?
Even a 70–90mm telescope shows Jupiter's two main dark cloud belts and its four bright Galilean moons. A 6-inch or larger scope adds more belts, moon-shadow transits, and the Great Red Spot when it faces Earth.
Do I need a telescope to enjoy it?
No — Jupiter is a brilliant naked-eye object, and ordinary binoculars already reveal its four largest moons as tiny points beside it. A telescope is a bonus, not a requirement.
Do I have to look on February 11?
No. Jupiter looks essentially the same for weeks around opposition, so any clear night from late January through March gives a superb view. Aim for when it's high, near midnight.
