when will halley's comet return

Halley’s Comet is expected to return to the inner solar system and be visible from Earth again around July 2061 , with peak activity and brightness in mid to late summer 2061.

Quick Scoop: Key Facts

  • Next return: Late July 2061 (perihelion around July 28–29, 2061).
  • Last appearance: It was last visible from Earth in 1986.
  • Orbital period: Halley’s Comet orbits the Sun roughly every 75–76 years.
  • How bright will it be? It’s expected to be much brighter and closer than in 1986, likely visible to the naked eye under dark skies.
  • Best viewing window: Northern Hemisphere observers should get better views in June–July 2061, with the main “show” starting around mid‑June and improving into late July.

Mini Timeline

  1. 1986: Last close pass near the Sun and Earth, but viewing was underwhelming due to geometry and distance.
  1. 2023–2024: The comet reached aphelion (its farthest point from the Sun) and began its journey back toward the inner solar system.
  1. 2060: It passes relatively near Jupiter, then heads inward toward Earth’s orbit.
  1. June 2061: Visible in morning skies, initially faint, then growing brighter as it approaches the Sun.
  1. Late July 2061: Reaches perihelion (closest to the Sun) and makes its best, brightest appearance for Earth observers.

Why It’s a Once‑in‑a‑Lifetime Show

  • A typical human lifespan only overlaps with one really good Halley’s Comet pass, so 2061 is likely the “big one” for most people alive today.
  • In 1986, the comet was on the far side of the Sun from Earth, making it dimmer and harder to see; in 2061 it will be on our side , which should boost brightness significantly (estimates around magnitude −1, brighter than most stars).

Think of 1986 as the “teaser trailer” and 2061 as the full cinematic release: same comet, much better viewing angle and proximity.

Little Extra: How to Think About the Date

  • If you remember 1986, add about 75 years to get 2061.
  • As of 2026 , that means we’re about 35 years away from its expected return.

TL;DR: If you’re wondering “when will Halley’s Comet return?” — mark your calendar for July 2061 , when it should swing past the Sun and put on its best show for Earth in more than a century.
