Significats de angular diameter en anglès

They were of equal size: perhaps twice the angular diameter of the full Moon as seen from Earth.

The angular diameter, as in the case of Betelgeuse, is in remarkably close agreement with the diameter predicted from theory.

Interferometer measures, now in progress on Mount Wilson, indicate that its angular diameter is about 0.020 of a second.

This cone, in fact, is very narrow, the angular diameter of the moon is so small compared to the diameter of the orb of day.

Its angular diameter of 0.040 of a second would thus correspond to a linear diameter of about 400 million miles.

To test the perfection of the adjustment, the telescope was turned to other stars, of smaller angular diameter, which showed the fringes with perfect clearness.

After Piazzi, Olbers, and Harding had discovered the small planets, Ceres, Pallas, Juno, and Vesta, he applied himself to the measurement of their angular diameters.

25), as the most favorable of all stars for measurement, and the last-named had given its angular diameter as 0.051 of a second of arc.
