ok,
not sure where to ask this but I'm a teacher who dabbles in programming and I'm writing a program to illustrate transfer orbits etc and needed the orbital elelments of the planets and found them here. I just need clarification if the "L mean longitude" tells me where the planet was on the date specified. ie earth's mean logitude is 100.5. Does that mean that earth is 100.5 degrees from the perihelion? Please say yes so I'm on the right track  or how far am I off? Any direction is appreciated cheers jb |
