@kchangnyt I have severe reservations about trusting a science article that suggests that Venus orbits the Earth.

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.

LSST claims it can detect asteroids closer to horizon and has done simulations showing that. Yet to be demonstrated in practice.

Cutoff close to 'horizon' is due to looking through greater depth of the atmosphere. Look up the term 'airmass''. /1

We’re not really disagreeing over anything. Yes, harder to see close to horizon. But can see closer than many assumed.

Planet or Asteroid, size matters. Size of telescope does not directly scale to size of object it can resolve, specially /2
