Izhdubar is an asteroid in the Apollo orbit class. Its orbit takes it from 0.74 AU to 1.27 AU from the Sun; one orbit takes 369 days. Discovered 19 November 1993 by Shoemaker, C. S., Shoemaker, E. M.. Orbit from the JPL solution of 30 January 2024.

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.

Izhdubar was an ancient Chaldean sun-god. He was responsible for slaying the dreaded dragon Tiamat, which personified primeval chaos and was hostile to gods and men. The exploits of Izhdubar are thought to represent the sun's annual passage through the twelve signs of the zodiac.

Close approaches 127 on record
Top-down view of the ecliptic, Earth at the centre, for the 2083-11-08 16:18 UTC close approach of Izhdubar. Catalogue miss distance 187.2 LD · 7.2 × 10⁷ km. The curve is the geocentric path from 2083-11-05 to 2083-11-11, 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. At closest approach the object is north of the ecliptic. The path is a geocentric ecliptic ephemeris from JPL Horizons. The inset is a heliocentric view and is approximate.
