Astro::Catalog::Query::MPC - A query request to the Minor Planet Center's Minor Planet Checker.

This module provides an object-oriented interface to the Minor Planet Center's Minor Planet Checker webform available at It stores information about asteroids found in a search radius at a specific epoch in an Astro::Catalog object.

The object will by default pick up the proxy information from the HTTP_PROXY and NO_PROXY environment variables. See the LWP::UserAgent documentation for details.

See Astro::Catalog::BaseQuery for the catalog-independent methods.
