I Plotting the orbits of the planets from Ephemeris data

AI Thread Summary
To plot the orbits of planets around the Sun using Ephemeris data from the JPL Horizons System, it is essential to include heliocentric distance information. Users can modify table settings to display the necessary columns, such as r (the object's distance from the Sun) and delta (the observer's distance). This data will enable the creation of accurate 2D orbital plots. The coordinate system used by the JPL Ephemeris is centered at the Solar System's barycenter, eliminating the need for coordinate transformation. Accessing the right data will facilitate effective plotting of planetary orbits.

TL;DR Summary
plotting the position of planets. Describe the orbits of the planets.
Using Ephemeris data from the JPL Horizons System.
I would like to plot the position of planets around the Sun for different dates and describe their orbits.
I got the Ephemeris data for each planet from the JPL Horizons System, I got:

Date__(UT)__HR:MN R.A.___(ICRF)___DEC Ang-diam ObsSub-LON ObsSub-LAT ObsEcLon ObsEcLat

however I could not figure out how to plot the orbit since I did not get any distance.
I would like to obtain dates, distance from the sun and the corresponding latitude to plot the 2D orbits.
I understand these the coordinate system of the JPL Ephemeris are centered at the barycenter of the Solar System, so in principle I would not need a coordinate transformation.

Any ideas or suggestions on how to get the data needed to plot the orbits?
Cheers,
Jor

You need to edit the table settings and choose heliocentric distance. This will be the objects distance from the Sun. You can also choose the observer distance. You should see the following columns added:

r__rdot__delta__deldot

with r being the objects distance to the sun, delta being the observers distance.

Today at about 4:30 am I saw the conjunction of Venus and Jupiter, where they were about the width of the full moon, or one half degree apart. Did anyone else see it? Edit: The moon is 2,200 miles in diameter and at a distance of 240,000 miles. Thereby it subtends an angle in radians of 2,200/240,000=.01 (approximately). With pi radians being 180 degrees, one radian is 57.3 degrees, so that .01 radians is about .50 degrees (angle subtended by the moon). (.57 to be more exact, but with...
