For the moon, I can write the following expression for the angularsize.
1
It must be noticed that the sun's apparentdiameter is not always the same.
2
The variation of the apparentdiameter corresponds (inversely) to the variation of distance.

They were of equal size: perhaps twice the angulardiameter of the full Moon as seen from Earth.
2
The angulardiameter, as in the case of Betelgeuse, is in remarkably close agreement with the diameter predicted from theory.

Its angulardiameter of 0.040 of a second would thus correspond to a linear diameter of about 400 million miles.
6
To test the perfection of the adjustment, the telescope was turned to other stars, of smaller angulardiameter, which showed the fringes with perfect clearness.
7
After Piazzi, Olbers, and Harding had discovered the small planets, Ceres, Pallas, Juno, and Vesta, he applied himself to the measurement of their angulardiameters.
