... Since A and B differ 9 in latitude and the circumference of Earth is given by 2r, the distance AB is given by AB = (2r/360) × 9 where r is the radius of Earth. Similarly, since the distance CD is 1/5 the solar diameter and the Sun subtends an angle of 30' or 0.5 at Earth, the angle is 0.1, wh ...

Observations and explorations of Venus
Observations of the planet Venus include those in antiquity, telescopic observations, and from visiting spacecraft. Spacecraft have performed various flybys, orbits, and landings on Venus, including balloon probes that floated in the atmosphere of Venus. Study of the planet is aided by its relatively close proximity to the Earth, compared to other planets, but the surface of Venus is obscured by an atmosphere opaque to visible light.
