What is Venus's distance from the sun? How many miles away from the Sun is the Earth? How far is Ceres from the sun? What distance is Pluto from the Sun in miles? What is the distance from Mars to the sun? How far are the outer planets from the Sun?
How long does it take light to travel from the sun to Mars? How many miles does one light year have? Hint: 1 mile = 1.61 km. How long is an astronomical unit in miles? How long would it take to travel to Alpha Centauri?
Much like Aristarchus, he used the phases of Venus to find the angles in a Venus-Earth-sun triangle. His more precise measurements for what exactly constitutes an AU were possible thanks to the existence of the telescope. Guessing (correctly, by chance) the size of Venus, Huygens was able...
The loneliness of the past year has been painful for many of the seniors. When the hot meals arrive, they get to talk with the volunteers and share stories. Sylius Toussaint is 81 and came from the island nation of Dominica in 1960, who said talking with the volunteers helps him as much...
Venus exhibits phases like the Moon. It is a lot further away, so it looks a lot smaller than the Moon. The phases are not visible to the naked eye, except to a very few sharp-eyed people; and were unknown until the advent of the telescope about 400 years ago. You cannot see the...
quest has been to determine the optimal number, times, magnitude, and direction of the impulses, to accomplish general three-dimensional (3D) multiple-revolution orbit transfers while minimizing the total Δv. This is Edelbaum’s heretofore not rigorously answered question [19]: How many impulses...
"It's harder than you think just to put a ruler on these images and figure out how big the sun is — [SDO] doesn't have enough precision to nail this down," NASA researcher Ernie Wright told Space.com. "Similarly, with the Mercury and Venus transits, it turns out [a measurement ba...
Mercury and Venus do not have moons. This is because any moon orbiting around them would be in an unstable orbit and would most likely be swallowed by the mammoth gravitational pull of our solar system’s mighty Sun. Whenever we look up at the night sky, we see a greyish-white object ...

Mars. Wednesday became dies Mercurii, with Mercury taking the place of Hermes. Thursday became dies Jovis, named for Jove (also known as Jupiter), the Roman equivalent to Greek head honcho Zeus. Friday became dies Veneris, named for Venus, the Roman’s version of Aphrodite, goddess of love...
