Parsec was a very cool video game that I played long, long ago on my TI 94A computer.Įxcellent info. Wonderful stuff, mathematics-I even still remember some of it after more than fifty years since graduation. Yes, indeedy, after all the mathematical fooling around to prove that we really knew trigonometry, it came out to exactly 3.26 light years. The definition of a parsec was: "That distance at which the diameter of the Earth subtends one second of arc" When I was a freshman, we were required in physics to determine the value of a parsec. Is the parsec a relative vector which is adapted to a conventional parameter?Ī comment on Hank's definition of parsec:Ī parsec is the distance at which the diameter of the Earth's orbit, (not of the Earth itself as Hank mistakenly writes) subtends an angle of 1 arc second. I read a book at one time, about 20 years ago, which presented a figure of 63,000 miles as the distance of a parsec.(at least I think that was the statement it was 63 followed by zeros).
If your friends or guests prefer to use a gamepad, it should work out of the box, but some additi.
I always wondered what a parsec was! Thanks, very interesting! The Parsec app enables gamepad input to be passed from client to host using our virtual USB driver. It is commonly used to measure the distance. A mile is a unit of distance equal to 5,280 feet or exactly 1.609344 kilometers. One way to understand parallax is to look at a nearby object and note its position against a wall. It is exactly 648,000/ astronomical units, or approximately 30.9 trillion kilometers. Explanation: Parallax is a method of using two points of observation to measure the distance to an object by observing how it appears to move against a background. October 30, anon29051: You have also mistakenly written the definition.Ī parsec is the distance at which one astronomical unit (roughly, the radius, not the diameter) of the Earth's orbit, subtends an angle of 1 arc second.Īpril 12, anon16328. A parsec is a unit of distance used in astronomy. Solution Verified by Toppr Diameter of Earth’s orbit 3×10 11m Radius of Earth’s orbit, r1.5×10 11m Let the distance parallax angle be 1'4.847×10 6rad.
The answer for vctrphsr is a parsec is approx 31 trillion km as stated in the article and for your comment about relative vector: no.
