JWST will orbit the sun at a distance of 1 million miles farther than Earth, at a point known as the second Lagrange point
, or L2.
The service module of a lunar orbiter that flew back to Earth in November had been sitting in a position that brought in into sync with Earth's orbit, known as the second Lagrange point
Euclid will be in an orbit around the second Lagrange point
(L2) about one and a half million kilometres behind the Earth, when looking from the Sun, from where it will observe nearly all of the extragalactic sky (>15,000 degA) for a period of six years.
China's second moon orbiter, the Chang'e-2, sent back its first batch of data while orbiting the second Lagrange Point
(L2) about 1.
The satellite is now orbiting the second Lagrange Point
, nearly a million miles away from the Earth.
It is destined for a Lissajous orbit about the second Lagrange point
(L2) of the Earth-Sun system, 1.
With launch currently planned for mid-2007, this satellite will, after a coasting phase of several months, be stationed approximately 1 million miles from the Earth at a location called the second Lagrange point
in the Earth/Sun system and transmit data to Earth for a period of up to 4 years.
It has arrived at what is called the second Lagrange Point
, which is where gravity from both the Sun and Earth balances the orbit of the satellite.
The spacecraft has also just entered its final orbit around the second Lagrange point
of the Sun-Earth system, L2.
