sbdb¶
This module contains a wrapper for the SBDB (small-body database) interface of the astroquery package
Classes¶
|
Small-Body Database Query for retrieving various properties of a small body. |
- class SBDBquery(MPCcode: str | int, *args, **kwargs)[source]¶
Small-Body Database Query for retrieving various properties of a small body. Usefull for retrieving names and masses in conjunction with the MPC module.
- estimated_spherical_gravitational_parameter(density: float)[source]¶
Calculate a very simple gravitational parameter by estimating the object’s mass using a given density. Will raise an error if the body’s diameter is not available on SBDB.
- estimated_spherical_mass(density: float)[source]¶
Calculate a very simple mass by estimating the object’s mass using a given density. Will raise an error if the body’s diameter is not available on SBDB.
- property codes_300_spkid¶
Returns spice kernel number for the codes_300ast_20100725.bsp spice kernel.
Some objects may return a name instead of a number. These are objects specifically specified by name in the codes_300ast_20100725.bsp kernel.
See https://naif.jpl.nasa.gov/pub/naif/generic_kernels/spk/asteroids/aa_summaries.txt for a list of exceptions
- property diameter¶
Returns diameter of the small body if available
- property gravitational_parameter¶
Returns the gravitational parameter for the small body if available
- property name¶
MPC NAME DESIGNATION
- Type:
Short name in the format
- property object_classification¶
Returns the orbit class of the object for example Amor Group for Eros
- property object_info¶
Returns info about the object, including its designation and orbit class
- property shortname¶
MPC NAME
- Type:
Short name in the format
- property spkid¶
Returns the JPL SPKID, the related codes_300_spkid method returns a modified ID for the Tudat standard kernel
