Esta \u00f3rbita en torno a la Tierra facilita la reparaci\u00f3n y el mantenimiento del observatorio. Sin embargo, la Tierra y la Luna bloquean su visi\u00f3n de gran parte de los cielos en esa ubicaci\u00f3n.<\/p>\n<p>El telescopio que reemplazar\u00e1 al Hubble, el Telescopio Espacial James Webb, operar\u00e1 desde una distancia mucho mayor.

En esos puntos, las fuerzas de gravedad de la Tierra, la Luna y el Sol se equilibran mutuamente; por tanto, es f\u00e1cil mantener un sat\u00e9lite orbitando en la misma posici\u00f3n.<\/p>\n<p>Otros sat\u00e9lites, como el observatorio SOHO de la ESA, deben orbitar de cara al Sol todo el tiempo. Este observatorio est\u00e1 situado en el punto Lagrange L1 a 1,5 millones de km en direcci\u00f3n al Sol desde la Tierra.<\/p>\n<p>Puesto que la fuerza de atracci\u00f3n gravitacional de la Tierra y la del Sol se equilibran en el punto L1, el observatorio SOHO puede mantenerse orbitando continuamente entre ambos astros sin consumir una gran cantidad de combustible.<\/p>","protected":false},"excerpt":{"rendered":"<p>Most spacecraft are placed in orbits around the Earth.
