Cometary orbits usually have very large eccentricities, often approaching (or even exceeding) unity. Halley's comet has an orbital period of 76 yr and an orbital eccentricity of e=0.9673 (a) What is the semimajor axis of Comet Halley's orbit? (b) Use the orbital data of Comet Halley to estimate the mass of the Sun. (c) Calculate the distance of Comet Halley from the Sun at perihelion and aphelion. (d) Determine the orbital speed of the comet when at perihelion, at aphelion, and on the semiminor

52K views · 677 reactions | The solar system extends far beyond Neptune into two major cometary regions: the Kuiper Belt, a flat disk of short-period comets, and the Oort Cloud, a vast spherical zone of long-period comets. Kuiper Belt objects often follow elliptical orbits, while Oort Cloud comets tend to travel on parabolic or hyperbolic trajectories, sometimes making a single pass around the Sun before exiting the solar system entirely. | The Randall Carlson | Facebook

Why are the orbits of planets in our solar system expanding like the waistband of a midlife couch potato? It happens because the Sun’s gravitational grip gradually weakens as our star ages and loses mass. Now, a team of NASA and MIT scientists has indirectly measured this mass loss and other solar parameters by looking at changes in Mercury’s orbit.
