TYC 8998-760-1 - System
Simulates TYC 8998-760-1, a young star with two giant planets imaged on wide orbits. It is one of the few multi-planet systems seen directly. Both planets are still glowing from their formation heat.
Teegarden's Star - System
Simulates Teegarden's Star, a nearby ultracool dwarf with two Earth-mass planets in the habitable zone, among the closest potentially temperate worlds.
The 2029 Apophis Close Encounter with Earth
Simulates asteroid 99942 Apophis on its 13 April 2029 Earth flyby — 31,600 km up, inside geostationary orbit — using JPL Horizons states from 6 April 2029.
The All Seeing Eye
Simulates four equal masses whose overlapping paths draw an almond-shaped eye with a central focus. The periodic four-body solution has no central star; the shape is gravity alone.
The Chelyabinsk Impactor's Last Orbit
Simulates the Chelyabinsk impactor’s last weeks: a 17–20 m Apollo asteroid on its outbound solar orbit from 1 January 2013 until atmospheric entry over Russia on 15 February.
The Earth and Moon System
Simulates Earth and the Moon as a two-body system: the Moon at 384,400 km, tidally locked on a 27.3-day orbit, with the Sun included as the distant perturber.
The Figure Eight N-body Choreography
Simulates the Chenciner–Montgomery figure-eight: three equal masses tracing one closed curve, each offset by a third of a period, repeating forever under Newtonian gravity.
The Inner Solar System
Simulates Mercury, Venus, Earth, and Mars — the four rocky planets inside 1.5 AU — on their real heliocentric orbits around the Sun, with no outer giants.
The Kuiper Belt and Scattered Disc
Simulates the outer Solar System beyond Neptune: Pluto, Eris, Haumea, Makemake, Sedna and other Kuiper Belt and scattered-disc bodies on their eccentric, inclined orbits.
