A Simple Solar System Simulation

This notebook demonstrates some basic controls of the pywwt Jupyter widget in its 3D (really, 4D) Solar System mode.

First, we import the necessary modules:

In [ ]:
from pywwt.jupyter import connect_to_app
from astropy.coordinates import SkyCoord
from astropy import units as u
from astropy.time import Time

Next, we connect to the WWT app:

In [ ]:
wwt = await connect_to_app().becomes_ready()

Turn on the 3D Solar System mode and adjust a few view parameters, including significantly exaggerating the size of the planets to make them more visible:

In [ ]:
wwt.set_view('Solar System')
wwt.solar_system.scale = 99  # scale up the planet size very unrealistically!

Choose a nice angle that will show several planets:

In [ ]:
wwt.center_on_coordinates(SkyCoord(339.32980758, 20.78999814, unit=u.deg), fov=.6*u.deg)

Finally, set the time of WWT's internal clock and adjust its rate to make the planets move at a nice pace:

In [ ]:
wwt.play_time(rate=300000)  # 300,000 times faster than real time
