Detailed explanation-1: -The James Webb Space Telescope will not be in orbit around the Earth, like the Hubble Space Telescope is - it will actually orbit the Sun, 1.5 million kilometers (1 million miles) away from the Earth at what is called the second Lagrange point or L2.

Detailed explanation-2: -Caption. Webb will orbit the Sun near the second Sun-Earth Lagrange point (L2), which lies approximately 1.5 million kilometers (1 million miles) from Earth on the far side of Earth from the Sun. Webb will not be located precisely at L2, but will move in a halo orbit around L2 as it orbits the Sun.

Detailed explanation-3: -The James Webb Space Telescope (JWST), the largest and most powerful space-based telescope ever built, is orbiting the Sun at a distance of around one million miles from the Earth.

Detailed explanation-4: -This “halo orbit” around L2 is highly elliptical and is roughly perpendicular to its orbital path around the Sun. The distance between Webb and L2 varies between about 250,000 and 830,000 kilometers (150,000 - 500,000 miles). Because of this complex orbit , Webb’s precise distance from Earth varies over time.
