Question

Name a famous comet that can be seen every 75 or 76 years?

Answer 1

Halley’s comet can be seen every 75 or 76 years.

Halley’s comet is a periodic comet and returns to earth every 75 years. It is named after English astronomer Edmond Halley who studied this comet in the years 1531, 1607, and 1682. Initially, he thought that these were three different comets but later it was concluded that the same comet kept returning to the earth.

Halley’s comet is 8km wide and 16km long. It travels around the sun every 75 or 76 years in an elongated orbit. The last time when it passed close to the earth was in the year 1986. It is again expected in the year 2061.
