2061 is correct.
Halley's Comet is a short-period comet that returns to the inner solar system roughly every 75 to 76 years, which makes it visible to the naked eye from Earth.
It last appeared in 1986, and its next appearance near the Sun is expected in mid-2061. Edmond Halley first predicted its periodic return, which is why it carries his name.
