Q:

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? 

A:

Horizons Ephemeris generator can give you a planet's position and velocity vectors at a specified time. 
This is one set of possible options:

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

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.

You've probably long since moved on, but, just for reference, the 
initial conditions HORIZONS uses are mentioned ("header.431_572") in 
ftp://ssd.jpl.nasa.gov/pub/eph/planets/Linux/README.txt but the only 
place I could find them in "table form" is in my own git repository: 
https://github.com/barrycarter/bcapps/blob/master/ASTRO/header.431_572 
The values are explained in 
http://ilrs.gsfc.nasa.gov/docs/2014/196C.pdf starting on page 39, 
"VI.  Initial Conditions and Constants", especially in the tables 
starting with Table 4 on page 47 and ending with Table 13 on page 74.  
I've written scripts to setup the initial conditions and numerically 
solve the differential equations using Mathematica, so the following 
may be helpful:

https://github.com/barrycarter/bcapps/blob/master/ASTRO/bc-header-values.pl 
https://github.com/barrycarter/bcapps/blob/master/ASTRO/bc-integrate.m 
When I reduce the step size sufficiently (Mathematica's default step 
size is too large), my results closely match those of HORIZONS:
