10 trillion kilometers is approximately 6.2 trillion miles.
No, it is actually less than that. A light year is about 5.9 trillion miles. Earth's circumference at the equator is about 25,000 miles. So a light year would be equivalent to going around the world about 240 million times.
The stratosphere starts about 10 kilometers (6.2 miles) above the Earth's surface and extends up to about 50 kilometers (31 miles) high.
Sirius is approximately 8.6 light-years away from Earth, which is equivalent to about 8.2 parsecs or 25.4 trillion miles. This translates to roughly 8.6 x 10^4 astronomical units (AU).
In my opinion, yes. There are at least 10 billion trillion Earth-like planets in the observable universe.

Alpha Centauri B is about 4.37 light years away from our sun. One light year is about 5,878,625,373,183.61 (almost 6 trillion) miles away. So that means that Alpha Centauri B is about 25,689,592,880,812.38 (about 26 trillion) miles from our sun. If you look at it in kilometers one light year equals 9,460,730,472,580.8 km (about 10 trillion km). So that means that Alpha Centauri B is about 41,343,392,165,178.1 (about 41.5 trillion) kilometers away or about 41 petameters.
Light from an object a trillion miles away (10 to the power of 12) will take around 0.17 years to get to the observer or 62 days.
No, it is actually less than that. A light year is about 5.9 trillion miles. Earth's circumference at the equator is about 25,000 miles. So a light year would be equivalent to going around the world about 240 million times.
25 trillion = 25,000,000,000,000 or 2.5 x 10^13 miles.
10 light-years is 58,785,000,000,000 (58.785 trillion) miles.
The stratosphere starts about 10 kilometers (6.2 miles) above the Earth's surface and extends up to about 50 kilometers (31 miles) high.
Sirius is approximately 8.6 light-years away from Earth, which is equivalent to about 8.2 parsecs or 25.4 trillion miles. This translates to roughly 8.6 x 10^4 astronomical units (AU).
It is: 2.5*10^13 miles
No. The ozone layer sits in the Earth's stratosphere, 10 to 50 kilometers or 6 to 31 miles from the Earth's surface.
According to Wikipedia, a parsec is 30 trillion kilometers. So, a megaparsec is 30 million trillion kilometers. And, since there are about .62 miles in a kilometer, a megaparsec is about 19 million trillion (or quintillion) miles. More precisely, 1 parsec = 3.08568025 x 10^16 meters. So, 1 megaparsec = 10^6 * 3.08568025 x 10^16 meters or 3.08568025 x 10^22 meters. Converting to kilometers, a megaparsec is 3.08568025 x 10^19 kilometers. Converting to miles, a megaparsec is .621371192 * 3.08568025 x 10^19 miles or 1.91735282 x 10^19 miles. This is equivalent to 19.1735282 x 10^18 miles. Since 10^18 is a million trillion (or quintillion), 1 megaparsec = 19.1735282 million trillion miles.
In my opinion, yes. There are at least 10 billion trillion Earth-like planets in the observable universe.
