| 32. | It has been estimated to be ?distant from Earth ( by extrapolating from its angular diameter and estimated radius ).
|
| 33. | This is a red giant star with a stellar classification of M3 III . The measured angular diameter of this star is.
|
| 34. | Human eyes have a resolution limit of around 1 arc-minute, while the angular diameter of Venus is slightly larger.
|
| 35. | For example, a measured angular diameter of 55.6 mas corresponds to a Rosseland mean diameter of 56.2 mas.
|
| 36. | At its distance from the Sun, the Sun's angular diameter is reduced to a tiny disk about 2 arcminutes across.
|
| 37. | The D ? relation, used in elliptical galaxies, relates the angular diameter ( D ) of the galaxy to its velocity dispersion.
|
| 38. | The sun's angular diameter is about 1920 arcseconds and we are only talking about a change of about 20 arcseconds in altitude.
|
| 39. | The angular diameter of Deimos is only 2?times the angular diameter of Venus as seen from Earth during a transit of Venus from Earth.
