The Spaceguard Foundation (SGF) is a private organization based in Frascati, Italy, whose purpose is to study, discover and observe near-Earth objects (NEO) and protect the Earth from the possible threat of their collision.

Since then, it has moved into the ESA Centre for Earth Observation (ESRIN) at Frascati.

[3] As of 2007[update], Italian astronomer Andrea Carusi heads the foundation.

The Spaceguard System is a collection of observatories engaging in near-Earth objects (NEO) observations.

[4] The Spaceguard Central Node—the website of the foundation—manages the collection and provides the observatories with services which would optimize the international coordination of NEO followups.
