comets

A Python package for small bodies research

Julia-based thermophysical modeling (TPM) tool for asteroids.

A command-line tool for producing tables of the positions of solar system objects over time.

Moon Cheeser is an infinite runner where the player plays as a mouse gathering cheese pieces and avoiding craters and other astronomical objects, such as comets and planets, on a moon made of cheese.

The 5th Annual American Museum of Natural History Hackathon produced by the BridgeUP: STEM program

A comprehensive, modern web dashboard for NASA JPL’s Horizons System, transforming complex astronomical ephemeris, orbital mechanics, and spacecraft trajectory data into an intuitive, visual, and human-friendly experience.

A command-line tool for producing tables of the positions of solar system objects over time.

Gauss-Radau Small-body Simulator

NASA CAMS (Camera for All Sky Surveillance) Meteor Shower Portal by SpaceML

TicketSwap’s product component library

kepler is a C and Python astronomy library. It implements VSOP87 for the planets, ELP 2000-82B for the Moon, minor body calculations using the MPC database, IAU precession & nutation models, rise/transit/set, Moon phase, eclipse, and equinox/solstice calculations.

This version of the OrbFit package contains a modified orbit9 integrator. The integrator has been modified to integrate the spin axis dynamics of small asteroids, due to the YORP effect. At the same time, the Yarkovsky effect is modified according to the dynamics of the spin axis.

Fast precovery of small body observations at scale

Tails: chasing comets with ZTF and deep learning

A set of Matlab classes implementing popular gravitational models for asteroids and comets.

Asteroids 🪨 that will make a close approach by Earth 🌏 today

Multi-language library for converting packed/unpacked Minor Planet Center designations (asteroids, comets, satellites)

Les Houches Index of Small-Body Tools

This is a modified version of the N-body code mercury, by J. E. Chambers, that includes the Yarkovsky and YORP effects for the dynamics of small solar system objects.
