    Max Aphelion Distance of Kuiper Belt Comet w/216 yr Orbital Period

    Thanks, this makes sense :) I am still wondering why this is not a valid orbit for a periodic comet

    Max Aphelion Distance of Kuiper Belt Comet w/216 yr Orbital Period

    Is the definition of a Kuiper Belt object that it lies between 40 and 50 AU from the Sun?

    Max Aphelion Distance of Kuiper Belt Comet w/216 yr Orbital Period

    The major axis is 72 au and the max distance that the comet can be from the Sun is some number very close to 72, such that the orbit goes very close to the Sun at perihelon and very far away at aphelion 71.99 was just something I picked

    Max Aphelion Distance of Kuiper Belt Comet w/216 yr Orbital Period

    Okay so since the aphelion is the point where the comet is furthest form the Sun, the max aphelion is 71.99 AU, and then I can calculate the eccentricity of the orbit

    Max Aphelion Distance of Kuiper Belt Comet w/216 yr Orbital Period

    Homework Statement Find maximum possible aphelion distance for a Kuiper Belt comet with an orbital period of 216 years? What is the eccentricity of this orbit? What prevents a periodic comet from following this precise orbit? Homework Equations perihelion = a(1-e) aphelion = a(1+e) 2a =...

    Astronomy : Velocity of approach of the Sun's equator

    The sun's rotational period is 25 days at the equator. Given that the radius of the sun is 700,000 km, calculate the max velocity of approach or recession of the Sun's equator as viewed from Earth. Find the max change in wavelength of a spectral line due to the rotation and express it as a...
