I looked it up, and there's a discussion on FimFiction about the weight of a Ursa Minor. ​​​​

"Leonzilla: If we assume that the weight of that Ursa minor is relatively proportional to a bear. The scale to adjust is one of the following.

Polar Bear--- Brown Bear Average Weight of Mature Male) 900-1,500 pounds--- 500-900 pounds Heaviest Recorded ) 2,210 poun 2,500+ pounds Average Length of Mature Male) 8-8.4 feet >7-10 feet"

"Psionic: Let's think for a second: what is a Ursa (minor or major) composed of? Probably magic or energy or light. (Pick one.) The Ursa doesn't weight enough to create a crater everytime it walks or demolishes the house when it puts its weight on top of it. Even a building needs a strong foundation otherwise it would sink into the ground. But IT'S solid enough to crush the house when it bites it. The real question is, does it weight when it wants to?"

"In response to Psionic ​​​​​​Leonzilla:

Assuming that this houses are solid in the first place, which is a little questionable considering how often ponyville is left in to a wreck. Also assuming the density of the land is proportional to our own."

"In respone to Leonzilla Epsilon-Delta: Also, that's assuming a build similar to a black bear. It's about 3 times the size of a polar bear and up-scaled from that would weigh 2700- 4500 lbs. (on this scale the Ursa major could be up to 20,000 lbs!)"

"Nebula Star: So if I put the average pony at about 4 ft tall (Which would make Celestia a little over 6 ft, not counting the horn) That would make the Ursa Minor about 40 ft long of 5 times the polar bear. Cube it for volume and the ursa would be 125x the mass, assuming the same density. 500*125 = 62,500 kg and by my system that would require a MWC of a little over 1000 Kilolevs/sec to levitate.

In response to Epsilon I think you forgot to cube the ratio for the weight. Something 2 times the size in every dimension is 2^3 times the volume and so the mass if working with the same density."
