Star Wars Rebels Magazine #1
Kanan and Ezra throw asteroids at this villain's ship using the Force. It was released after Disney purchased Lucasfilm, so it is Disney canon.
This ship is 52.3 meters long according to the Star Wars wiki.
Height:
>300 / 188 = 1.59
>52.3 x 1.59 = 83.15 meters
>83.15 / 2 = 41.57 meters.
Length:
>197 / 188 = 1.04
>52.3 x 1.04 = 54.39 meters
>54.39 / 2 = 27.19 meters.
(4 × π × 27.19 × 41.57 × 27.19)/3 = 128732.15 cubic meters (128732150000 cubic centimeters.)
Most asteroids have a density of 5.32 grams per cubic centimeter.
128732150000 x 5.32 = 684855038 kilograms.
The ships in the comic are shown to be traveling fast enough to avoid asteroids. Asteroids move at 25 km/s on average, which would be 25000 m/s. The asteroids the two threw would have to move just as fast to hit the ship.
