The comet's closest approach to Earth occurred in 837, at a distance of 0.033 AU (3.07 million miles or 4.94 million kilometers). At that time, April 10, 837, Halley reached a total apparent brightness of about magnitude -3.5, nearly that of Venus at greatest brilliance. See more Until the time of English astronomer Edmond Halley (1656-1742), comets were believed to make only one pass through the solar system. But in 1705, Halley used Isaac Newton's … See more Each time Halley returns to the inner solar system its nucleus sprays ice and rock into space.

Determine the semi-major axis of the orbit of Halley’s comet, given that it arrives at perihelion every 75.3 years. If the perihelion is 0.586 AU, what is the aphelion? Strategy. We are given the period, so we can rearrange , solving for the semi-major axis. Since we know the value for the perihelion, we can use the ...
