can i get venus postion by using SDP4?

[hanchangdong]

In my project, I need to get the position of celestial bodies in real time, for example Venus&Moon&Sun which is in the solar system and Big Dipper which is further away.
Can i use SDP4?
Any suggestions, thank you.

SDP4 is meant for objects with periods > than 225 but definitely within Earth's gravity. That won't work for other celestial bodies. I'd recommend https://github.com/mgreter/ephem.js as a possibility or https://github.com/mourner/suncalc for sun/moon calculations.

Thanks a lot!
