WebAug 15, 2024 · The vicinity of the Sun-Earth L2 point is a good location for a spacecraft that observes the universe. Note that I wrote "vicinity of". The linear Lagrange points (L1, L2, and L3) are metastable. An immense amount of fuel would be needed to have a spacecraft stay at these points. It turns out that there are pseudo orbits about these points that ... WebThe James Webb Space Telescope is not in orbit around the Earth, like the Hubble Space Telescope is - it actually orbits the Sun, 1.5 million kilometers (1 million miles) away from the Earth at what is called the second …
WebThe distance of JWST from the L2 point varies between 250,000 to 832,000 km, as shown in Figure 1. The period of the orbit is about 6 months. The maximum excursion above or below the ecliptic plane is 520,000 km. The maximum distance from the Earth is 1.8 million km, and the maximum Earth-Sun angle is <33°.
WebL2 is further away than the Moon, almost 4 times further, I believe. The shadow of the Earth is teensy at that point, that's not why it's there. It's there because it's stable and it's able to point away from Earth, Moon, and Sun all at the same time and thus avoid our combined infrared interference.
