The average distance from the Earth to the Moon is about 1.28 light-seconds. This means it takes light about 1.28 seconds to travel from the Earth to the Moon.
The distance to the moon is about 1.3 light seconds or about 0.000000032 light years.
The moon is about 0.0000000406 light years away from earth. Clearly, the moon is MUCH too close (238,000 or 239,000 miles or so) for the distance to be rendered meaningfully in light years.
1.28 seconds at the moon's average distance from earth ... same as for a radio signal.
It takes approximately 1.28 seconds for light to travel around the moon, which means the circumference of the moon is roughly 6,783 miles. Traveling at the speed of light, you could make a full trip around the moon in about 2.56 seconds.
The average distance from the Earth to the Moon is about 1.28 light-seconds. This means it takes light about 1.28 seconds to travel from the Earth to the Moon.
Approximately 1.28 light seconds away from Earth is the Moon. The average distance between Earth and the Moon is about 1.28 light seconds.
At its average distance from the earth, the moon is 1.28 light seconds away.
The distance to the moon is about 1.3 light seconds or about 0.000000032 light years.
Moonlight takes 1 min 3 seconds to reach earth.
The moon is about 0.0000000406 light years away from earth. Clearly, the moon is MUCH too close (238,000 or 239,000 miles or so) for the distance to be rendered meaningfully in light years.
1.28 seconds at the moon's average distance from earth ... same as for a radio signal.
The average distance from the Earth to the Moon is 384,400 km retroreflectors have been placed on the moon and used to measure the distance by timing a pulse of light. the round trip time is about 2.5 seconds so a one way trip takes light about 1.25 seconds
The average distance to the Moon is 384,399 kilometres = 4.06318742 × 10-8 light years (Note the minus) The moon is only a tiny fraction of one light year from earth. It takes light from the sun eight minutes to reach earth, and the moon is much closer to earth than the sun. Measuring such a small distance in light years is possible but impractical. ======================================= The moon is roughly 1.27 light seconds from the earth. (rounded) 1.27 light seconds is the same as 0.0000000406 light year. (rounded)
It takes approximately 1.28 seconds for light to travel around the moon, which means the circumference of the moon is roughly 6,783 miles. Traveling at the speed of light, you could make a full trip around the moon in about 2.56 seconds.
My almanac lists the average distance from earth to moon as 384,401 km. Round trip = 768,802 km. Time = (distance) divided by (speed) = (768,802,000) / (3.8 x 108) = (7.68802 x 108) / (3.8 x 108) = 2.563 seconds (rounded)
The speed of light is 299,792,458 metres per second or "c". so d * 1,000 / c gives 1.2808861255609038703702145835837 seconds But classroom maths will put the speed of light at 300,000,000 meters per second. so d * 1,000/ c gives 1.28 seconds.
