If I was in a plane going 700 miles an hour how long would it take me to get there....In this life time?
I have to reach this star too...My wish must come true!

I think it was Casey Kesem that said "Keep your feet on the ground and keep reaching for the stars". You will reach that star someday. The journey might be difficult, but you will reach it.

Assuming the stars in the universe are distributed uniformly (a surprisingly good approximation when considering the universe): Consider the universe as a sphere of radius R which is equal to 13 Billion light years=13E9 cY where c is the speed of light 3E8 m/s. then the radius at which 1/3 of the volume of the stars in the universe is contained is r=R/(3^(1/3)) that is the radius of the universe divided by the cubed root of 3 or roughly 13E9 cY/1.44 That means the farthest star will have to fall a distance of 9.01E9 cY to fall to the earth. Now we know that it's impossible for massive objects to travel at the speed of light but let's assume that the stars fall at that speed just to put a lower limit on your question. so the time for 1/3 of the stars to fall to the universe is t=r/c=9.01 E9 years or 9 billion years. Now all this is assuming that the stars will immediately turn around and start falling to the earth but of course we all know that most stars in the universe are accelerating away from us in accordance with Hubble's law. But 9 Billion years is the absolute minimum amount of time it will take. Note that our answer did not depend on where we were in the universe seen it is isotropic from any vantage point. So this lower limit holds on every world in the universe.

The nearest star to Earth is the Sun. The nearest star to the Sun is Proxima Centauri. You would not be able to get there in this life going that slow.

You're wrong dear. The nearest star is the SUN. Never. If you were in a plane you wouldn't make it out of the atmosphere.

If you were flying in a plane at 700 mph, it would take you just over 4,076,973 years to get there. So, its not too bad, but you better start packing your bags pretty soon.

convert light-years to miles ... then since D=RT then T-D/R, so divide the light year distance in miles, but 700 and you will get the time in hours ... it will be a huge number. way longer than your lifetime. Wait for warp drive to be invented, or hitch a ride with ET.

Assuming you want to travel 25 trillion miles, flying at the approximate speed of the space shuttle (25,000 MPH), it would take about 114 years. Hurry! Book your flight right away!

You first have to get away from earth's gravitational pull for which u will need acceleration of abt 11Km/s(I dont remember the figure correctly) and not just speed.

best way to reach it - close ur eyes and imaging ur self travelling at super speed towards that star,,, and in no time u will be there.....
good luck

forever. 700 mph are approx 0.3 km/sec, you need to increase your speed to 15km/sec to escape the gravity of the sun.
