Where can I find a set of data of the initial conditions of our solar system?

  • As the title suggests, I'm in need of a set of data of our solar system. Similar to this http://bima.astro.umd.edu/nemo/archive/#iau25, but more specifically, the Dubinsky Milky Way-Andromeda data.

    I'm creating a n-body simulation for school and can't seem the find any initial particle conditions that I could use to simulate our solar system in the software I'm developing. I need initial positions, velocity and mass.

    Any idea where I could find this?

    Horizons Ephemeris generator can give you a planet's position and velocity vectors at a specified time.

    This is one set of possible options:

    enter image description here

    Clicking Generate Ephemeris on that page will give you position and velocity vectors:

    enter image description here

    Above the position and velocity vectors are the Julian date as well as the more conventional date.

    Wikipedia can give the masses of the sun and planets.
