How many Suns would it take, laid side by side, to reach a star 5.0 light-years away?
Diameter of sun = 1.392 x 106 Km
= 1.392 x 109 m
One light year is distance equivalent to the distance that light travels in one year.
One light year = 9.4607 × 1015 m
5 light year = 47.3 × 1015 m
numbers of sun = 5 light year distance / diameter of one sun
= 47.3 × 1015 / 1.392 x 109
numbers of sun = 33.98 x 106

Light from the star Betelgeuse takes 640 years to reach Earth. How far away is Betelgeuse in units of light-years? a. Betelgeuse is 980 light-years away. b. Betelgeuse is 640 light-years away. c. Betelgeuse is 1900 light-years away. d. Betelgeuse is 520 light-years away.
5. You are traveling from star A to the identical star B that is 5.0 A light years away. During the trip, both stars explode and emit the same wavelength. You detect the light while passing in front of another planet O that is halfway between the stars A 2.5 ly 2.5 ly 0 and B. You detect the light coming from the explosion of A as red (A-750 nm) and the light coming from the explosion of B as...
Suppose you decide to travel to a star 69 light-years away at a speed that tells you the distance is only 28 light-years. Part A How many years would it take you to make the trip? Express your answer using two significant figures.
The nearest star to Earth is Proxima Centauri, 4.3 light-years away. Part A At what constant velocity must a spacecraft travel from Earth if it is to reach the star in 4.9 years, as measured by travelers on the spacecraft? b: How long does the trip take according to Earth observers? in years
In an Earth reference frame, a star is 76 light-years away. How fast would you have to travel so that to you the distance would be only 39 light-years?
The nearest star to Earth is Proxima Centauri, 4.2 light-years away. Part A At what constant velocity must a spacecraft travel from Earth if it is to reach the star in 3.9 years, as measured by travelers on the spacecraft? Express your answer using two significant figures. v=_____c Part B How long does the trip take according to Earth observers? Express your answer using two significant figures. t=_____ years
The nearest star to Earth is Proxima Centauri, 4.3 light-years away. At what constant velocity must a spacecraft travel from Earth if it is to reach the star in 5.3 years, as measured by travelers on the spacecraft? Express your answer using two significant figures. C is the answers unit. How long does the trip take according to Earth observers? Express your answer using two significant figures. years is the answers unit.
Light requires 4.5 years to travel from the nearest star to earth. If we could travel there in a spaceship going 90% of the speed of light, the trip would require 5.0 years according to clocks on earth. How much time would pass for the passengers in the ship?
How fast (as a percentage of light speed) would a star have to be moving so that the frequency of the light we receive from it is 14.0 % higher than the frequency of the light it is emitting? Would it be moving away from us or toward us? (Assume it is moving either directly away from us or directly toward us.)
How many years does it take for a deposit of $1000 to reach $3450 with an annual effective interest rate of 14.5%? Answer correct to 4 decimals. Redo Problem #1 above, compounding for each complete year, but using simple interest for any remaining fraction of a year at the end. (This is what is actually done in practice.) Answer correct to 4 decimals.
