How big is Ceres compared to Pluto? How many Plutos can fit in Earth? How far is Alpha Centauri from the Sun? An object takes 45 years to orbit the Sun. What is its average distance (in AU) from the Sun? What is the distance between asteroids in the asteroid belt?
How long would it take to travel to Alpha Centauri? How was an astronomical unit first measured? How many kilometers equals one astronomical unit? How far away can the Hubble Space Telescope detect galaxies? How far away is the Andromeda Galaxy from Earth?
So the apparent brightness of Alpha Centauri with its angular diameter of 0.007″ would be the same as if we viewed a piece of the Sun masked off to a diameter of 0.007", though it is so much closer to us? If alpha Cen is basically of the same stellar type like the sun (i.e.ide...

If one traveled at the speed of light, he could make a round trip to Alpha Centauri in nine years. But, even at that speed, he could not reach Alcaid (北斗星) in the handle of the Big Dipper. A one-way journey to Alcaid would take almost 200 years 1.阅读理解 (4.0) 分 In ...
Accurate astronomical distance determination is crucial for all fields in astrophysics, from Galactic to cosmological scales. Despite, or perhaps because of, significant efforts to determine accurate distances, using a wide range of methods, tracers, and techniques, an internally consistent astronomical di...
"In fact, if you were to shrink the sun to the size of a sand grain, the distance to the nearest star would be measured in miles," Sally Dodson-Robinson, a planetary scientist at the University of Delaware, previously told Mashable. The nearest solar system is Alpha Centauri, located 25...
This square is 10 to the 16 metres, the distance light travels in one year, one light year. Here’s our closest neighbour, Alpha Centauri. Three stars for the price of one, with planets orbiting around them. I’d love to know what’s going on there. ...
How far away is Alpha Centauri from Earth? How far above the Earth is the Hubble Space Telescope? What is Uranus' distance from the sun? How far can light travel in one year? What is the speed of the Earth around the sun in m/s? What is the speed of the Earth around the sun in...
The nearest star to our solar system is 4.29 light-years away. How much is this distance in terms of parsecs? How much parallax would this star (named Alpha Centauri) show when viewed from two locations of the Earth six months apart in its orbit around th ...
