Scenarios
Exoplanets
Confirmed exoplanet systems from the NASA Exoplanet Archive, built from published orbital elements. Browse from single-planet hosts to compact multi-planet systems such as TRAPPIST-1, and watch how real architectures hold together under Newtonian gravity.
XO-2 N - System
Simulates XO-2 N, a Sun-like G-type star of 0.96 solar masses, and XO-2 N b, a 0.59-Jupiter-mass companion, with an orbital period of 2.6 days, at 0.037 AU from its star.
XO-2 S - System
Simulates XO-2 S, a Sun-like G-type star of 0.98 solar masses, and XO-2 S b, a 0.26-Jupiter-mass companion, with an orbital period of 18.2 days, at 0.135 AU from its star, on an eccentric orbit (e ≈ 0.15).
XO-3 - System
Simulates XO-3 b, a massive hot Jupiter on a tilted, eccentric orbit. Its spin-orbit misalignment is evidence that the planet was scattered inward. The planet is roughly twelve times Jupiter's mass.
XO-4 - System

XO-5 - System
Simulates XO-5, a Sun-like G-type star of 1.04 solar masses, and XO-5 b, a 1.19-Jupiter-mass companion, with an orbital period of 4.2 days, at 0.051 AU from its star, and an equilibrium temperature near 1,230 K.
XO-6 - System
Simulates XO-6, a Sun-like F-type star of 1.47 solar masses, and XO-6 b, a 4.40-Jupiter-mass companion, with an orbital period of 3.8 days, at 0.082 AU from its star, and an equilibrium temperature near 1,577 K.
XO-7 - System
Simulates XO-7, a Sun-like G-type star of 1.41 solar masses, and XO-7 b, a 0.71-Jupiter-mass companion, with an orbital period of 2.9 days, at 0.044 AU from its star, and an equilibrium temperature near 1,743 K.
YZ Cet - System
Simulates YZ Cet, a cool M-dwarf of 0.14 solar masses, and YZ Cet b, a 0.7-Earth-mass planet, with an orbital period of 2.0 days, at 0.016 AU from its star, and an equilibrium temperature near 471 K, on an eccentric.
alf Ari - System

bet Cnc - System
Simulates bet Cnc, an orange K-type dwarf of 1.70 solar masses with 1 confirmed companion (bet Cnc b) on NASA archive orbits.
bet Pic - System
Simulates Beta Pictoris, a young star with a famous debris disk and two imaged giant planets. Beta Pic b was the first exoplanet whose spin was measured.
