I'm trying to teach myself about calculating orbits of Comets and Asteroids and their positions I am thinking of ordering Orbital Mechanics by John Prussing and Astronomical Algorithms by Jean Meeus. Does any recommend these books or some other book? Is there any websites recommendations for...

Ok I have been away for a while trying to get past the next step, but I'm not having much luck in finding out how to do it. I would like to be able to calculate velocity and distance and position at a given time. if you can point me in the right direction a website or a book/video that would...

ohhhhhhhhhhhhhhh its a good thing my webcam is off I have a big red face. yes works great now I also had to deg2rad the angle. thank you for your help

I'm having a problem with the value for r. r should not be smaller than 2.053207 or larger than 5.1849075431599 right? I calculate 2.053207 AU r_\mathrm{per}=(1-e)a\!\, 5.1849075431599 AU r_\mathrm{ap}=(1+e)a\!\, also shouldn't r_\mathrm{ap}-r_\mathrm{per}= asemi-major axis a...

Thank you, your answer made it very clear to me, now that I know about AU/yr vs km/s.

Thanks for the reply I have less then 15 posts so I can't post the link yet, but the wiki page I am talking about is the same one you posted. This is right on the page. So I used period in years. for elliptic orbits: 4 \pi^2 a^3/T^2 = \mu (with a expressed in AU and T in years, and with...

I live in Japan we one you can feel almost everyday

Checking on wiki as I am trying to teach myself about orbits \mu = GM Standard gravitational parameter On Wiki I also see that \mu = 4\pi^2a^3/T^2 Standard gravitational parameter but when I calc them they do not match using the above orbital elements I get \mu = 39.478417604357 when...

Im trying to learn how to calculate orbits. Comet 17P Holmes e: 0.432668 q: 2.053207 Ascending Node: 326.8586 w: 24.2856 Inclination: 19.1134 Epoch: 2454600.5 (2000) Tp: 20070504.5695 I can calculate Semi Major Axis, Semi Minor Axis, semi-latus rectum, Period in years a =...

we would have less light pollution at night for observing with telescopes. We would have no more Lunar or Solar Eclipses.

Hello I have a question about calculations of orbits. Mostly my question is about Comet orbits and eccentricity and period. To help myself learn more about orbits I'm witting a simple calculator for myself so I can better grasp it. I'm getting the orbital elements from the MPC website ( I...
