Glossary term: Apolo
Description: La palabra Apolo tiene dos significados en astronomía. El primero se refiere al programa Apolo que puso a los primeros seres humanos en la superficie de la Luna. Estas misiones estaban propulsadas principalmente por el cohete Saturno V. En total, se lanzaron catorce misiones numeradas (Apolo 4-17); once misiones iban tripuladas y nueve de ellas se dirigieron a la Luna, de las cuales seis realizaron alunizajes y las otras tres orbitaron la Luna.
Por otro lado, también se conoce como Apolo a un grupo de asteroides cercanos a la Tierra, que debe su nombre al asteroide (1862) Apolo. Este grupo de asteroides se caracteriza por tener un semieje mayor superior a la distancia Tierra-Sol de una unidad astronómica (UA) y con distancias de perihelio inferiores a 1 UA. Esto significa que, durante sus órbitas, los asteroides Apolo se desplazan desde el interior de la órbita terrestre hacia el exterior de la misma, aunque estos asteroides rara vez se acercan a la propia Tierra.
