The 2021 James Webb Space Telescope will orbit 930,000 miles from earth in "Mars-ward" direction

 from SPACE dot-com article

NASA's James Webb Space Telescope will be more extreme than its famous predecessor in a variety of ways, including its cosmic locale.

The $10 billion Webb is considerably bigger, more complex and more powerful than the Hubble Space Telescope, which has been studying the heavens from Earth orbit for more than three decades. 

And the new observatory, which is scheduled to launch on Dec. 25, 2021 will be going much farther afield as well — all the way out to the Sun-Earth Lagrange Point 2 (L2), about 930,000 miles (1.5 million kilometers) from our planet in the Marsward (not sunward) direction.
