Can humans breathe on Europa? “Europa has an extremely thin oxygen atmosphere — far too thin for humans to breathe.” Can humans live on Europa? “The type of life that might inhabit Europa likely would not be powered by photosynthesis –...
What did Aristarchus need to measure in order to estimate the size of the Moon? “Aristarchus (a busy guy!) also devised a way to calculate the distances and sizes of the Sun and Moon. Therefore, the Moon’s diameter is 2/7 that...
Who Discovered size of moon? “The jump Aristarchus made from terrestrial measurements of scale to the celestial is truly remarkable. Without any measures of the sizes of or distances to any celestial objects, he was able to measure both for the...
How to find distance between Earth and moon using trigonometry? “⇒θ1+θ2=θ is the parallax angle. Hence, the distance of the Moon from the Earth is calculated to be bθ1+θ2 .” How do you measure the distance from the Moon to the...
