A light year is the (a) it takes light to travel in one year.
A light year is a unit of
time
distance
frequency
electricity
If Distance=speed X time and we know that it takes light 500 seconds to reach Earth from the Sun, how far is the Sun?
(hint: speed of light =186,282 miles per second.)
(a)
If distance=speed X time and we know that the Space-X Falcon-1 rocket can travel 25,000 km/hr, how long (in years) will it take to reach Alpha Centauri (our nearest star outside of the Milky Way galaxy?) hint: Alpha centauri is 4.24 light year from Earth, 1 light year=63, 241 astronomical units, and 1 astronomical unit=149, 597, 871 km
(a)
If alpha centauri, the nearest star outside the Milky Way galaxy, is 1 light year away, how long will it take for light to travel to alpha centauri, in months?
(a)
A distance that is equivalent to 5.879 trillion miles or 9.461 trillion km and is used to measure distances to space objects outside of our solar system.
Light year
Astronomical unit
A distance that is the equivalent of 92, 900,00 miles or 149,600 km, and is the distance from the center or the Sun to the center of Earth, and is used to measure distances between space objects within our solar system.
