The asteroid belt in our solar system was not discovered until long after the invention of the telescope on Earth. The next planet out is Threshold. A large planet that would seem to correspond to our Jupiter, this would also appear as a very bright star. Jupiter is the next brightest object in the Earth's night sky after Venus, and I expect that Threshold, like Jupiter, would be the next brightest object in Abode's night sky after Cauldron. Its motion across the sky is similar to Homestead's, but it travels more slowly.
Threshold has several moons, just as Jupiter does.
Seen alone, Threshold's moons would appear to be average to dim stars. The planet Gateway seems to correspond to our own Saturn. It would also appear as a bright star in Abode's sky, moving like Homestead or Threshold but much more slowly. Less noticeably different than Homestead or Threshold, Skywise might have had to study the sky for a while before realizing that this star wanders, too. The next planet out, Outerreach, is similar to our Uranus or Neptune.
