Context. "Telescope can't see objects orbiting the earth." "But but but amateurs can see Venus!"

Article says “within Earth’s orbit,” not “orbiting the earth."

Venus is closer to sun than Earth and therefore within Earth’s orbit. Pretty straightforward and correct, yes?

Very much so. Apparently I'm not good at words today. My apologies.

Ok, thanks.

Disagree. Context is visibility of asteroids 'inside' Earth's orbits, not of planets. Makes zero sense in context. /1

There is no cutoff to visibility at Earth’s orbit. (What Myhrvold said Mainzer said.) Are you saying there is?

for small (faint) the sky brightness (background) also scales up >> signal to noise plateaues. Thus planets irrelevant. /3.
