Answer: 6.5 light-years = 61,452,657,210,672 km.
Answer: 30 light-years = 283,627,648,664,640 km.
6.5 ly is approximately 61,493,434,600,000 km from earth or 61.5 trillion km.
Approximately 6.15 x 1013 kilometers
The distance from Earth to a star is not enough information to tell when it will burn out. When it does burn out, though, we will still be able to see it for 65 more years.
It would take 65 years 11 months to travel to Aldebaran from Earth traversing at the speed of light.
The distance that light travels in a vacuum in one year, approximately 9.46 trillion kilometers or 5.88 trillion miles. Thus, the distance light can travel in 15 years is more than 88 trillion miles.
According to my Honors Earth Science high school textbook (McDougal Littell: Earth Science by Nancy E. Spaulding and Samuel N. Namowitz), the far side of the moon's crust, at about 150 kilometers, is approximately 85 kilometer's thicker than its near side, at 65 kilometers thick.
Aldebaran is an orange giant star located about 65 light years away in the zodiac constellation of Taurus.It has a temperature of about 4,010 Kelvin.
Approximately 65 light-years.
This star is about 65 light years from Earth.

65 Million years
Canopus is the brightest star in the southern constellation of Carina.It is approximately 320 light years from Earth which is about 3 x 1015 km or 1.88 x 1015 miles.See related link for more information.
65 million years
dinosaurs roamed the earth about 65 million years ago.
Any unit of length can be used; for example the official unit of length, which is the meter. However, to avoid having to write large numbers, the following three units are often used in astronomy: (1) The astronomical unit, the average distance between Earth and the Sun. Used mostly for measurements within the Solar System. (2) The light-year; the distance light travels in a year. Approximately 9.5 x 1015 meters. (3) The parsec. A star at this distance would appear to have a parallax of one arc-second. Equal to approximately 3.26 light-years.
Earth did not exist 65 billion years ago. However 65 million years ago an asteroid collided with Earth, triggering a mass extinction even that wiped out a wide variety of organisms, including the dinosaurs.
65 kilometers=6,500,000 centimeters
they were on earth for more than 1,000,000 years ago
