How much anti-matter in an anti-matter engine would it take to get to Alpha Centauri?

That depends on where you start and how much mass you want to take there. There are two many variables to make a guess. In general, because matter-antimatter conversion to energy results in a huge amount of energy (assuming that the antimatter is used in a matter-antimatter drive of some sort), it wouldn't take much.

(tenth of the speed of light) An anti-matter engine alone probably would get you very far, so using a solar sail to get it moving, and then turning on the anti-matter engine would make more sense. Assuming the ship got to around 0.2 C, (if you have a braking system) it would take 21 years to get to Alpha Centuari. That's not bad considering the fastest man-made object today, the Voyager 1, would take over 70,000 years to get to the star. In the movie Avatar, the ship, (the ISV Venture Star) took only 6 years to get to Alpha Centauri, travelling at 0.7 C, and taking place in the year 2154. The ship also ran on an anti-matter engine. So if you got a good start you would need around 6,000 grams of anti-matter (not really that much) to go on a one-way trip. The problem is anti-matter is so hard to make that the amount we have today is only around 20 nanograms. (1 nanogram = 1 billionth of a gram) Unless we are able to come up with a more efficient way to make anti-matter, we are not going to be able to go to Alpha Centauri any time soon, little alone the year 2154.

If you traviled at the speed of light how long would if take to get to Alpha Centauri?
4.37 years.
What is one Habitable planet near alpha centauri?
None that are known. There may be a roughly Earth-sized planet in orbit around Alpha Centauri B, but this planet, if it exists, would be far too hot to support life.
How long does it take light to travel from Alpha Centaury the nearests star to your sun to your solar system?
4.3 light years===========================Sorry. "Light year" is an answer to "how far", not "how long".Alpha Centauri is about 4.4 light years away from our solar system and everything in it,which means that it takes AC's light about 4.3 years to get here.
How long does it take for a radio transmission to go from earth to alpha centauri and back?
Light makes the trip to Alpha Centauri in about 4.3 years. The star system is about 41 trillion kilometers from earth. At 40,000 km / hr it would take 1 billion hours travel time, which is roughly 114,000 years.
Why would it take long for alpha centauri light to reach earth?
along long long long time
How far to alpha centurus?
That would be "Alpha Centauri". The distance is about 4.4 light-years.
Which star is most like sun?
There will be hundred's. The closest would be Alpha Centauri A
If you traviled at the speed of light how long would if take to get to Alpha Centauri?
4.37 years.
What is the name of the closet star to are planet?
The sun of course! But if you mean beyond that, it would be Alpha Centauri

What is farther from Earth Alpha centauri or the sun?
That's actually an easy calculation, if you state the problem correctly. Alpha Centauri is about 4.5 light years away. There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 365.24 days in a year. Multiply all those numbers together to find out how many light-seconds it is to Alpha Centauri. The Moon is about 1.5 light seconds away, so divide by that to get the ratio.
If you were travelling thought space at 70000 kilometers per hour how long it take to get to the star system Alpha Centauri?
Assuming that you start from earth, travelling that slowly to Alpha Centauri would take quite a bit of time. Alpha Centauri's about 4.367 light years away, which means at the suggested speed of 70,000 kilometers per hour, it would take you 673.26 centuries to get there. You definitely want to go much faster to get there.

How long does it take a starship traveling at half the speed of light to get to Alpha Centauri?
First of all, there has never yet been any such thing known to earth as a starship. If an object left Cape Canaveral at 1/2 the speed of light, and maintained a straight-line course toward the place where Alpha Centauri would be when it got there, it would reach Alpha Centauri after the clock on the launch-pad had ticked off 8.8 years.

What is the 3rd closest star on earth?
ANSWER:With the Sun being the first, Proxima Centauri is the next closest at 4.22 light years away in the Alpha Centauri star system. See the related link for more information.
