It is difficult to answer the question since Canis Major (the great dog) is a constellation, not a single star. The constellation contains a very large number of stars and other cosmic objects which have no astrophysical relationship with one another. It is simply that they are located in such a direction, and are so far away, that they appear to move together. The distances to the cosmic objects that make up Canis Major range from 8.6 light years to 8,400 light years. You can take your pick as to which number in that range represents the distance to Canis Major.
no it doesn't as far as i know
The scorpion constellation is made up of star that are different distances from Earth, so you can't find a single distance of a whole constellation.
No. It is far too hot and the pressure far too great
No Earth-like planets have been discovered yet, but our best telescopes are (so far!) incapable of locating any extra-solar planets that small. With the launch of the James Webb Space Telescope, this may change.
4k miles, if you mean how far can it be seen from space, rephrase.
He lives in a dome on earth far into the future.
The tree is at the far left next to Snoopy's dog house.
As far as I can find, No U.S.A. state has the beagle as its state dog. Pennsylvania almost chose the beagle, but opted for the Great Dane instead.
As far as man-made objects go, the Great Wall of China
that's depending on how far you are away from earth to look at the great wall of china
Depends on the dog. $10 is for a small dog like a chihuahua $15 is good for a medium sized dog like a spaniel and $20 for a large breed like a lab and $30 for a giant like a great dane.Or you can vary your price on how far you walk the dog.
The circumference of the earth is roughly 25,000 miles along any great circle.
