The telescope's mirror is 6.5-meters in diameter, compared to Hubble's 2.4-meter mirror. It will observe from the Earth–Sun L<sub>2</sub> Lagrange point, which is 1.5 million kilometers above the Earth. This point is well beyond orbit of the moon, which is 400,000 kilometers from the Earth. | The telescope's mirror is 6.5-meters in diameter, compared to Hubble's 2.4-meter mirror.
