Earth sun l2
WebJan 21, 2024 · At Sun-Earth L2, the Sun and Earth (and Moon, too) are always on one side of space, allowing Webb to keep its telescope optics and instruments perpetually shaded. This enables them to get cold for infrared sensitivity, yet still access nearly half the sky at any given moment for observations. WebNormally yes, but the balance of the combined gravitational pull of the Sun and the Earth at the L2 point means that Webb keeps up with the Earth as it goes around the Sun. The gravitational forces of the Sun and the …

However, there are orbits around L2 that are stable (or very nearly so). A craft in such an orbit requires far less fuel to maintain its orbit compared to a craft stationary relative to L2.
WebOct 18, 2024 · The L2 point is perhaps even easier to understand from the perspective of an inertial frame. Beyond the less massive body, the acceleration vectors toward the two massive bodies both point toward the center of mass. At distances very close to the less massive body the net acceleration is too great. WebJan 24, 2024 · L2 is located one million miles from Earth.
