How do you convert light years to scientific notation?
How do you convert light years to scientific notation?
When numbers are large, it is best to use scientific notation.
- For example: If you knew that an object was approximately 14.2 x 1014 miles away from Earth, how many light years would that be?
- Use the miles conversion factor: 1/(5.88 x 1012)
- Multiply: (14.2 x 1014) x (1/(5.88 x 1012)) = 2.41 x 102 = 241 light years.
How many miles are in a light-year in scientific notation?
A light-year, alternatively spelt lightyear, is a unit of length used to express astronomical distances and is equivalent to about 9.46 trillion kilometers (9.46×1012 km) or 5.88 trillion miles (5.88×1012 mi).
Is a light-year written in scientific notation?
A light year is the number of miles light travels in one year, about 5,880,000,000,000 5 , 880 , 000 , 000 , 000 . That is a lot of zeros, and it is easy to lose count when trying to figure out the place value of the number. Using scientific notation, the distance is 5.88×1012 5.88 × 10 12 miles.
How fast is a light-year in miles?
186,000 miles per second
It travels at 186,000 miles per second (300,000 km/sec). And thus a light-year is 5.88 trillion miles (9.46 trillion kilometers).
What are light years equivalent to?
approximately 6 trillion miles
A light-year is a measurement of distance and not time (as the name might imply). A light-year is the distance a beam of light travels in a single Earth year, which equates to approximately 6 trillion miles (9.7 trillion kilometers).
What number is 5.879 E 12?
A lightyear is the distance that light travels in one year. Since there are various definitions for the length of a year, there are correspondingly slightly different values for a lightyear. One lightyear corresponds to about 9.461e15 m, 5.879e12 mi, or 63239.7 AU, or 0.3066 pc.
How far away is the Andromeda Galaxy in scientific notation?
In scientific notation, we’d simplify it to 1.5 x 1019 miles.
What is 1 light year equal to in Earth years?
about 6 trillion miles
A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km). One light year is equal to the distance that light travels in one year (it is about ten trillion kilometers, or six trillion miles). One light years is equal to approx 6.5×10^5 earht s years.
What is 1 light-year equal to in Earth years?
How do scientists measure light years?
In a vacuum, light travels at 670,616,629 mph (1,079,252,849 km/h). To find the distance of a light-year, you multiply this speed by the number of hours in a year (8,766). The result: One light-year equals 5,878,625,370,000 miles (9.5 trillion km).
