Astronomy and Python

Python provides several different libraries and approaches that can be used to calculate the positions of objects in the solar system. Here I will give you a brief review of these tools and libraries:

Skyfield

Skyfield is used for accurate, modern, and Pythonic interfaces for astronomy computations. Best for modern, accurate planetary positions with ephemerides.

Skyfield description

Skyfield is a high-level astronomy library that provides precise positions of planets, stars, and other objects over a long period of time. It fetches ephemeris data directly and computes positions using vector algebra. Due to its accuracy, it is highly recommended for solar system objects.

Works with multiple timescales (UTC, TDB, TT). Fetches ephemeris data (de421, de422, etc.) for high-precision calculations. Can calculate the positions of satellites, planets, and stars.

Skydield installation

It is possible to install Skydield via pip and conda (via conda-forge) environments

PIP


pip install skyfield

CONDA


conda install -c conda-forge skyfield

Astropy

Astropy can provide astronomy-related calculations with detailed units and time handling. Great for working with celestial coordinates and time, although it requires external data for planets.

Astropy description

Astropy is a broad library that supports a variety of astronomy computations, including time conversions, celestial coordinates, and object positions. It's useful for converting between different celestial coordinate systems and performing basic astronomical calculations.

The most important part of astropy, it can easily communicate with other libraries to fetch ephemeris data for solar system objects.

Astropy installation

PIP


pip install astropy

CONDA


conda install astropy

Pyephem

Python-Ephemeris can be used for fast and efficient astronomical calculations for solar system objects. Goog for very fast for basic planetary positions, rise/set times.

Pyephem description

Pyephem is an older but highly efficient library that uses the same algorithms as the XEphem astronomy program. It calculates the positions of the Sun, Moon, planets, and stars very quickly but with slightly less accuracy than modern libraries like Skyfield or Astropy.

Pyephem can calculate the positions of stars, planets, and comets. Also, it can calculate rise, set, and transit times.

Pyephem installation

It is possible to install Pyephem via pip and conda (via conda-forge) environments

PIP


pip install pyephem

CONDA


conda install -c conda-forge pyephem

Spiceypy

Spicepy is a NASA SPICE Toolkit for Python, which is extremely precise in planetary and spacecraft navigation and research-level astronomy. Goog for highly precise, used in space missions, but more complex.

Spiceypy description

SPICE (Spacecraft Planet Instrument C-matrix Events) toolkit was developed by NASA and is widely used in mission planning and data analysis for interplanetary missions. Spiceypy is the Python wrapper for this toolkit. It provides access to ephemeris data, spacecraft position, and instrument pointing.

Spiceypy can provide mission-grade accuracy for positions and orientations. It has access to a vast set of planetary data (kernels). Can be suitable for long-term simulations and space mission data.

Spiceypy installation

It is possible to install Spiceypy via pip and conda (via conda-forge) environments

PIP


pip install spiceypy

CONDA


conda install -c conda-forge spiceypy

JPL Horizons, Astroquery

JPL Horizons can be used for accurate solar system positions with up-to-date data from JPL (NASA Junior Premier League). It is not a library, it is an online service, which can be accessible via Astroquery. Goog for accurate, up-to-date ephemeris from JPL, though online access is needed.

JPL Horizons description

JPL Horizons is an online tool that provides highly accurate ephemeris data for solar system objects, including planets, moons, asteroids, and comets. You can access this tool programmatically via HTTP requests or through libraries like Astroquery.

JPL Horizons are extremely accurate ephemerides from NASA JPL. You can query both past and future positions of objects. It supports coordinates in many systems and timescales.

Astroquery for JPL Horizons installation

It is possible to install Astroquery via pip and conda (via conda-forge) environments

PIP


pip install astroquery

CONDA


conda install -c conda-forge astroquery

Py-vsop87, VSOP87

Py-vsop87 (Very accurate Positions for Planets) is used for the calculation of the positions of planets using analytic series. Good for a lightweight solution to calculate planetary positions based on theoretical models.

Py-vsop87, VSOP87 description

VSOP87 is a theoretical model of planetary motion that can be implemented in Python using available algorithms. It provides the positions of planets based on a mathematical series expansion.

Py-vsop87 Provides positions for the major planets. A lightweight approach without needing large ephemeris files. Slightly less accurate than JPL ephemerides but adequate for many uses.

Py-vsop87 installation

PIP/GIT


pip install git+https://github.com/architest/py-vsop87.git
