Halley's comet appeared in the years 1758, 1834, 1910 and 1986. What year will it appear next?

Answer 1

Let's see now, uh, 76 years from 1758 to 1834, another 76 years to 1910, and another 76 to 1986... what's next? I know, it's 2012, I heard that a big comet is supposed to blow up Earth.

But it fact, the next perihelion is expected in 2061, not 2062. Funny, huh?

Answer 2

The average period of Halley's orbit is 76 years but you cannot calculate the dates of its reappearances by simply subtracting multiples of 76 years from 1986. The gravitational pull of the major planets alters the orbital period from revolution to revolution. Nongravitational effects (such as the reaction from gasses boiled off during its passage near the Sun) also play an important, but smaller, role in altering the orbit. Between the years 239 BC and 1986 AD the orbital period has varied from 76.0 years (in 1986) to 79.3 years (in 451 and 1066).

That being said, in early 2062...

Answer 3

1986+76=2062

Answer 4

Halley's comet is on a 76 year cycle. It's next expected on 2062.

Answer 5

a woman who starts off menstruating as youthful as 9 years previous is considered to be interior the diversity of medically "commonly used" sexual progression. it can not be elementary, yet there are surely boys who start to strengthen diverse sexual emotions and understand their orientation as youthful as 10.

Answer 6

The year of 2062.

Answer 7

It appears every 75 years and if I didn't goof with my math it should be about 2061.

Answer 8

mid-year 2061 - see http://en.wikipedia.org/wiki/Halley%27s_comet

Good Luck!!! (it will be a little less than 76 years - see you then).

Answer 9
