<p>Supplement to address Carl's question: <br>
</p>
<p>Remember that the earth totally eclipses the moon (when suitably
aligned), which is about 1/4 million miles away and has a ~2000-mi
diameter (3,468 KM). So, at 1 million miles distance (4 times the
Earth-Moon distance) the earth could eclipse an object that has a
500 miles diameter. SO, the telescope will truly be a piece of
cake in that shadow.</p>

would be fried (electronics burned) if it ever sees the sun.
So L2 places it in such a way that the Earth blocks the sun
