Lightyear isn't about time, it's distance. One lightyear is ten trillion kilometers.
the new planet goldilocks 20 lightyears away is most like earth but MAYBE in about 20 million years mars will be just like earth
If you are travelling at exactly lightspeed, to travel 20 light years (remember, this is a distance measurement) would take you exactly 20 earth years.The distance of one light year is the distance a light ray has travelled (within a vacuum) after one earth year.DEPENDS DON'T FORGET ABOUT TIME DILATION AT ROUGHLY 80%c 1 SEC IN YOUR OWN FRAME OF REFERENCE WOULD BE EQUIVALENT TO ROUGHLY 2-3 EARTH YEARS SO IF YOU TRAVELED AT 80%c FOR 7 SEC YOUR TIME ROUGHLY 20 YEARS WOULD HAVE PASSED ON EARTH HOWEVER 20 YEARS YOUR TIME YOU WOULD AGE 20 YEARS BUT TIME ON EARTH WOULD BE 70-80,000 YEARS FROM THE POINT YOUR 20 YEARS BEGAN
Sunlight takes about 8 minutes and 20 seconds to reach Earth, which is approximately 93 million miles (150 million kilometers) away. In terms of lightyears, this distance is about 0.00001581 lightyears, as one lightyear is roughly 5.88 trillion miles (9.46 trillion kilometers). Thus, sunlight travels a minuscule fraction of a lightyear to reach our planet.
20 lightyears, divided by 32 miles.
How much of the earth's surface do mountains cover? it is 99% of the earth
On Mars, a 20 year old would be the same age as on Earth since age is measured based on Earth years. However, a year on Mars is longer than a year on Earth, approximately 1.88 Earth years. So, if a person celebrated 20 years on Mars, in Earth years, they would be around 10.64 Mars years old.
7 years. but it passes through your system in 2-3 days undigested
about 20%
The Sun's distance to Earth won't change significantly in 20 years.
20 light years
There have been tsunamis through all of Earth's history. They did not just start in the past 20 years.
It would all depend on the speed travelling, as time = distance/speed.
