About Halley's Comet Returns
Halley's Comet — the most famous comet in history — returns to the inner solar system in 2061, with perihelion predicted for July of that year. This is the longest countdown on this site: a clock ticking toward a sky event most people see exactly once in a lifetime.
Halley orbits the Sun every 75–79 years, and it is the only naked-eye comet that reliably returns within a human lifespan — which is why it threads through history like a recurring character: embroidered into the Bayeux Tapestry in 1066, feared as an omen for centuries, and finally understood when Edmond Halley predicted its 1758 return, proving comets obey Newton's laws. Mark Twain was born under it in 1835 and, as he predicted, "went out with it" in 1910.
The 2061 apparition is forecast to be notably better than the disappointing 1986 pass — the comet will be positioned on the same side of the Sun as Earth, potentially shining brighter than the brightest stars. Until then, Halley sends annual postcards: both the Eta Aquariid (May) and Orionid (October) meteor showers are debris from its tail. Anyone born after the mid-1980s is waiting for their first look; the children of 2061 will remember it forever.
FAQ
When will Halley's Comet return?
Perihelion is predicted for mid-2061, with naked-eye visibility in the months around it — the countdown above tracks the long wait.
When was Halley's Comet last seen?
Its last perihelion was February 1986 — a relatively poor apparition. The 2061 return is predicted to be much brighter.
How often does Halley's Comet appear?
Every 75–79 years, depending on planetary perturbations — the only bright comet that reliably returns within a human lifetime.
Can I see pieces of Halley's Comet now?
Yes — the Eta Aquariid meteor shower each May and the Orionids each October are debris shed from Halley's orbit burning up in our atmosphere.
