From your location
See how high it is right now, whether it is up after civil twilight, and when it rises and sets where you are.
Your location stays in your browser and is sent only for this calculation. Using a what3words address is optional; if you do, the three words go to what3words to be converted and we don't record them. Set a location first, then you can save an email alert for this object. See our privacy policy.
Two-body approximation, good to about a degree for the planets — enough to find the constellation and know whether it is up.

Top-down view of the ecliptic, Earth at the centre, for the 2040-01-30 17:36 UTC close approach of 2007 CS5. Catalogue miss distance 26.5 LD · 1.02 × 10⁷ km. The curve is the geocentric path from 2040-01-27 to 2040-02-02, with a mark at UTC midnights and an arrow for the direction of motion. The circle is the Moon’s mean orbit; the Moon is plotted at closest approach. A ray shows the Sun’s direction. The labelled distance is the full separation. The drawn radius is the part that lies in the ecliptic plane. The path is a geocentric ecliptic ephemeris from JPL Horizons. The inset is a heliocentric view and is approximate.
