What's in the sky tonight: planets, Moon phase, dark hours and best objects to see

For your place and date: sunset, when it gets properly dark, the Moon's phase and rise and set times, where each planet is, and the best galaxies, clusters and nebulae for your eyes, binoculars or telescope.

Plan a night under the stars in one page

Before you carry a telescope outside, or just step out with binoculars, you want to know a few things. When does it get dark? Is the Moon going to wash out the sky? Which planets are up, and when are they highest? What’s worth pointing at? Sky tonight answers all of these for your exact place and date. It works it out on your device from accurate orbits, and it keeps working without an internet connection.

How to use it

  1. Set your place. Pick a city, type your latitude and longitude, or press Use my location. Your location stays on your device. Tick Remember my place to keep it for next time.
  2. Pick the night. The date is the evening the night starts. After midnight, the page still shows the night you are in.
  3. Read The night: sunset, the hours when it is properly dark (the Sun more than 18° below the horizon), sunrise, and the Moon’s phase and rise and set times.
  4. Planets and the Moon shows when each planet rises, when it is highest (and how high), and when it sets, with its brightness (magnitude) and constellation. The chart draws their height through the night over the sky colour: day, twilight and full dark.
  5. Best deep-sky objects lists galaxies, clusters and nebulae that climb above the height you choose while it is dark, brightest first. Choose what you observe with and the list changes to suit. Tap any object to open its full altitude chart.
  6. Download the night as an image, PDF or Word file to take outside or print.

What the numbers mean

  • Magnitude (Mag): brightness. Smaller is brighter, and negative is very bright. The eye reaches about 5 to 6 under dark skies, binoculars about 8 to 9, and a small telescope 10 to 12.
  • Highest: the time the object crosses your meridian (due south from the northern hemisphere, due north from the southern) and its height then. Objects are clearest when high, because you look through less air.
  • From Moon: the angle between the object and the Moon. Faint objects close to a bright Moon are hard to see.

Worked example

From Toronto on the night of 7 November 2026, the Sun sets at 17:00 and it is properly dark from 18:38 to 05:24. The Moon is only 1% lit, two days before new Moon, and doesn’t rise until 06:31: a dark night all night. Saturn is best in the evening (highest at 21:45), while Jupiter rises around midnight and is high before dawn. The binocular list starts with the Pleiades, the Beehive Cluster and the Andromeda Galaxy.

Questions

Where does the object list come from? The catalogue holds all 110 Messier objects and about 440 bright NGC and IC objects from the OpenNGC catalogue (CC BY-SA 4.0, Mattia Verga). Positions are J2000, and the page works out where they are tonight.

Why is a planet greyed out? It is never more than 10° above the horizon during the night, or it is too close to the Sun to see.
