requirements are *numpy* and *matplotlib*.\n\n\n## How to use\n\nAn example of simulating the inner planets:\n\n```python\nfrom gravitational.simulation import Simulation\nfrom gravitational.solar_system import initial_state\nfrom gravitational.constants import Constant\n\n# Define the time as a datetime object or a string (default now)\nt = '2021-02-17 04:26:00'\n\nsim = Simulation(t)\nc = Constant()\n\n# Get initial states from Horizons API\np0_sun, v0_sun = initial_state('sun', t)\np0_venus, v0_venus = initial_state('venus', t)\np0_earth, v0_earth = initial_state('earth', t)\n\n# Add bodies\ns = sim.add_body(name='Sun', color='y', size=25, mass=c.m_sun,\n                 position=p0_sun, velocity=v0_sun)\n\nv = sim.add_body(name='Venus', color='k', size=8, mass=c.m_venus,\n                 position=p0_venus, velocity=v0_venus)\n\ne = sim.add_body(name='Earth', color='b', size=10, mass=c.m_earth,\n                 position=p0_earth,
