classmethod SOLAR_SYSTEM_BARYCENTER() → float

Return the effective gravitational parameter of the Solar System barycenter as approximated by adding the gravitational parameters of the Sun, Mercury, Venus, Earth, Moon, Mars, Jupiter, Uranus, and Neptune.

This should only be used for calculating osculating elements with respect to the Solar System barycenter.

Horizons’s effective gravitational parameter (as of 2025-11-26) for osculating elements with respect to the Solar System barycenter is 1.3289051882019876E+11 km^3/s^2 which agrees to within 1e-6 with the value calculated here. Discrepancies are likely due to the inclusion of small bodies not included in the calculation here.

Returns:

mu – The gravitational parameter of the Solar System barycenter in au^3 / day^2.

Return type:

float

class adam_core.coordinates.origin.Origin(table: Table, **kwargs: int | float | str)

Bases: Table

code

A column for storing large strings (over 2³¹ bytes long). Large string data is stored in variable-length chunks.

classmethod from_OriginCodes(code: OriginCodes, size: int = 1) → Origin

as_OriginCodes() → OriginCodes

Convert the origin codes to an ~adam_core.coordinates.origin.OriginCodes object.

Returns:

Origin codes as an ~adam_core.coordinates.origin.OriginCodes object.

Return type:

OriginCodes

mu() → ndarray

Return the gravitational parameter of the origin.

Returns:

mu – The gravitational parameter of the origin in au^3 / day^2.

Return type:

~numpy.ndarray (N)

Raises:

ValueError – If the origin code is not recognized.
