Nettet$\begingroup$ Strong suspicion here that the reply attributing to Halley 'a rough estimation of the gravitational effects of Jupiter and Saturn' makes a confusion with the 1750s work of Clairaut et al. Halley's contributions seem to have been to identify the probable periodic nature of a number of comets, and to calculate them on a parabolic or possibly …

Answer: From the definition for c as c = (a 2 – b 2) 1/2 we have c = 17.1 AU and so the perihelion distance is just d = 17.8 – 17.1 = 0.7 AU. Since 1 AU = 150 million km, it comes to within 105 million km of the Sun. dennis tierney facebookUntil 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 theories of gravitation and planetary motions to compute the orbits of several comets. Halley found the similarities in the orbits of bright … Se mer Each time Halley returns to the inner solar system its nucleus sprays ice and rock into space.
