Webb's Orbit - Science@NASA
Webb orbits the sun 1.5 million kilometers (1 million miles) away from the Earth at what is called the second Lagrange point or L2. (Note that this graphic is not to scale.) James Webb Space Telescope orbit as seen from above the Sun's north pole and as seen from Earth's perspective.
Where Is Webb? NASA/Webb - Webb Space Telescope
During Webb's launch, deployment and commissioning, this page tracked Webb's current state in detail on its journey from Earth to entry into its L2 halo orbit through all steps of its deployment, during its cooldown to operational temperatures, through its instrument commissioning and finally to the delivery of its first science images.
James Webb Space Telescope - Wikipedia
Webb operates in a halo orbit, circling around a point in space known as the Sun–Earth L 2 Lagrange point, approximately 1,500,000 km (930,000 mi) beyond Earth's orbit around the Sun. Its actual position varies between about 250,000 and 832,000 km (155,000–517,000 mi) from L 2 as it orbits, keeping it out of both Earth and Moon's shadow.
Webb's Orbit at Sun-Earth Lagrange Point 2 (L2) | Webb
2021年5月19日 · Webb is not located at L2, but instead orbits L2, completing one circuit every 168 days. 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).
Where is Webb? - NASA
This page tracks Webb on its roughly 1,000,000 mile journey from Earth to entry into its L2 halo orbit as well as showing Webb's most recently completed deployment state. Flight data begins flowing right after launch vehicle separation about 30 minutes after liftoff.
Telescope Overview - Webb
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.
