Red Dwarf Flyby of the Solar System
Simulates a 0.12-solar-mass red dwarf on a hyperbolic flyby 40 AU from the Sun, with all eight planets and major dwarf planets in their January 2025 configuration.
Ross 128 - System
Simulates Ross 128 b, a temperate Earth-mass planet about 11 light-years away. Its quiet red-dwarf host is a neighbor of Proxima Centauri. It receives a similar amount of starlight to the Earth.

Simulates Ross 176, an orange K-type dwarf of 0.58 solar masses, and Ross 176 b, a 4.6-Earth-mass planet, with an orbital period of 5.0 days, at 0.046 AU from its star, and an equilibrium temperature near 682 K.
Ross 458 - System
Simulates Ross 458, an orange K-type dwarf of 0.56 solar masses, and Ross 458 c, a 6.00-Jupiter-mass companion, at 1,100 AU from its star.
Ross 508 - System
Simulates Ross 508, a cool M-dwarf of 0.18 solar masses, and Ross 508 b, a 4.0-Earth-mass planet, with an orbital period of 10.8 days, at 0.054 AU from its star, on an eccentric orbit (e ≈ 0.33).
SPECULOOS-3 - System
Simulates SPECULOOS-3 b, an Earth-sized planet on a 17-hour orbit around an ultracool dwarf. It is a nearby laboratory for bare, roasted rock. The host is only about 55 light-years away.
SWEEPS-11 - System
Simulates SWEEPS-11, a Sun-like G-type star of 1.10 solar masses, and SWEEPS-11 b, a 9.70-Jupiter-mass companion, with an orbital period of 1.8 days, at 0.030 AU from its star.
SWEEPS-4 - System
Simulates SWEEPS-4, a Sun-like G-type star of 1.24 solar masses, and SWEEPS-4 b, a 3.80-Jupiter-mass companion, with an orbital period of 4.2 days, at 0.055 AU from its star.
Saturn and Its Moons
Simulates Saturn with Titan, Enceladus, Mimas, and its other major moons, plus thousands of gravitationally interacting ring particles from the D ring to the F ring.
Shoemaker-Levy 9 Impacts Jupiter
Simulates comet Shoemaker-Levy 9’s 21 fragments slamming into Jupiter in July 1994 at 60 km/s, with the Galilean moons and Sun in the same gravity field.
Square Within a Circle
Simulates four equal masses whose paths form a square rotating inside a circle. No central body anchors the motion — the pattern comes from mutual Newtonian gravity alone.
TAP 26 - System
Simulates TAP 26, an orange K-type dwarf of 1.04 solar masses, and TAP 26 b, a 1.66-Jupiter-mass companion, with an orbital period of 10.8 days, at 0.097 AU from its star.

Simulates TCP J05074264+2447555, a Sun-like G-type star of 0.59 solar masses, and TCP J05074264+2447555 b, a 0.06-Jupiter-mass companion, at 0.940 AU from its star.
TESS: Earth–Moon Orbit
Simulates TESS in its 13.7-day high-Earth ellipse in 2:1 resonance with the Moon — perigee 108,000 km, apogee 376,000 km — above the Van Allen belts.
TIC 139270665 - System
Simulates TIC 139270665, a Sun-like G-type star of 1.03 solar masses, and TIC 139270665 b, a 0.46-Jupiter-mass companion, with an orbital period of 23.6 days, at 0.163 AU from its star, and an equilibrium temperature.
