How long would it take to get to Sirius in a spacecraft traveling at 120 km per second?
About 21,485 years
How long would it take to get to GJ 1214 b at the speed that voyager 1 is traveling?
I believe it would take 44,470,261 years at 17 Km/s, the current speed of Voyager 1 according to Wikipedia
How long does Sirius take to orbit the sun?
Sirius does not orbit the Sun.
How long would it take a laser beam to go from earth to Sirius?
Since sirius is 8.6 light years away and light travels at the speed of light including lasers then guess what?? It's gonna take 8.6 years...
How long does it take light from Sirius and from barnard's star to reach the earth?
Sirius 8.6 yearsBarnards Star 6 years
How long does it take Sirius B and Siruis to orbit each other?
About forever. If it were even aimed that direction, which it's not.Voyager is further from Earth than any physical man-made object ever, and it's still moving away from the Sun faster than any other physical man-made object, so it's in no danger of being overtaken anytime soon.However, it's still very, very near the Sun by interstellar distance standards.It takes light from the Sun about 17 hours to reach Voyager 1.However, Sirius is about 8.3 light years from the Sun ... that is, light from the Sun takes about 8.3 years to reach Sirius. That's about 17,500 times further away than Voyager is, and Voyager's been traveling since 1977. So, quick back of the envelope calculation ... it will take Voyager over 600,000 years to get as far away from the Sun as Sirius is, and as mentioned it's not pointed in the right direction to get to Sirius (or any other nearby star); according to NASA it's headed vaguely in the direction of the constellation Ophiucus.
How long would it take to get to Neptune in a spaceship?
If you take a jet it will be 513 years, 2 months. With rocket it is 12 years,3 months
The Voyager 1 spacecraft is currently about 18.5 billion km from the Earth. How long does it take in seconds for a radio signal to get from Voyager 1 to Earth?
That distance you gave is nearly 200 astronomical units so if that is right the time would be 8 minutes times 200, which is 26½ hours.
How long would it to Sirius in a space shuttle?
Space shuttles are not designed to operate outside of a low-earth orbit, where they are protected from deadly radiation by the earth's magnetic field; a mission to Sirius by a space shuttle is not even possible. For more information on the earth's radiation protective field, see the Wikipedia article:Van Allen radiation belt
How long would it take the satellite to reach Neptune?
How long it would take to get to Neptune from Earth would depend on the path chosen and on where Neptune and Earth were in their orbits when the mission was launched. For example, the Voyager 2 spacecraft was launched on Aug 20, 1977 and it reached Neptune on Aug 24, 1989. So, Voyager 2 took about twelve years to reach Neptune.
How long does it take Sirius to move 1 degree across the sky?
I think it is a fixed-star so it stays in the same spot relative to our perspective.
Was Sirius Black in Harry Potter and the Philosopher's Stone?
