At the time of referring how far is alpha centaur from earth We must consider that if we speak in terms of kilometers, we must do the math very well, since a light year is approximately 9.461.000.000.000 km, then multiplying by 4,36 would give an amount of 41.249.960.000.000. XNUMX km and this would be what your journey would take.
How far is Alpha Centaur from Earth?
Before mentioning how far this alpha centaur is from earth, it is important to note that this part of the cosmos is more than a triple star system o constellations, which according to various studies is the closest to our solar system since it is 4.22 light years away. In this order of ideas, this set of stars in turn is made up of two more alphas, that is, alpha centauri A and B, which are 4,36 light years away.
The Journey to Alpha Centauri
We already know that there is at least one star in Alpha Centauri, the closest star to the Sun. And, taking into account that Alpha Centauri is actually a formula made up of three stars most likely there are many more. Since we saw the news of the discovery, many have wondered how long it would take to travel to Alpha Centauri to see the new world for ourselves.

How far is alpha centaur from the earth and which in turn is the one that is closest to the solar system it could be said that it lasts for twenty or thirty years. A long time, yes, but less than the average life of any person. Space travel is indeed difficult, an adventure of its own in truly evolved varieties. However, let's analyze the useful choices more calmly.
The precipice of space space
The most vertiginous human object that we have expelled out of the Solar system it is Voyager 1. This honorable probe is moving away from the Sun at a speed of 17,4 km/s, or about 540 million kilometers per year. But Alpha Centauri is 4,37 light-years away—or 272 celestial units, a digit that yields to 000 light-years in the case of the Proxima Centauri girl. At this speed, Voyager 4,24 would be about 1 years behind in reaching Alpha Centauri, assuming it walked toward it. Needless to say, Voyager is not a very suitable starship.
With usable technology it would be the potential to send a spacecraft out of the Solar System five to ten times lighter than Voyager 1. The serious exposed of the NASA to fix 'interstellar' probes capable of working the Oort Cloud or the heliopause, he warns of achieving a journey of 150 million kilometers in fifteen or thirty years. Well, it seems that we are prospering, until we realize that this distance does not reach 000% of a light year. We pursue the same as the initiation.
To get to Alpha Centauri within a tolerable time, the speeds we have to achieve must be 130 kilometers per second. At that speed we would reach 100 years, which can presume some annoyance or another taking into account the habit that most of us have of dying before the age of 25.000. If we travel at 50 km/s, the flight time is subjected to XNUMX years.
Half a century is not bad for a trip space, so this should be the speed we must consider when achieving, quite a challenge if we perpetuate Voyager 1 bobbing at less than 18 km/s.
It is clear that we have no other compensation than to use different impulse systems than the usual ones, so we had better forget about the supposed chemical launch used by ordinary projectiles. Why? Well, since if we want to achieve 1% of the speed of light (3000 km/s) using agreed chemical rockets, we would need 1026 kg of flammable for each kg of mass of the ship. In other words, that ship would end up having 100 times the mass of the Earth.
In another order of ideas, if we want to travel to Alpha Centauri in this century we must make certain atonements. For example, leave out the driven ships. Machine probes will be vastly lower and harder. At the same time, we can imagine a mission that is confined to passing the Alpha Centaur without hardship to placate and enter orbit near one of the two primordial stars, which would conjecture an exorbitant powerful consumption.
Hot nuclear and ionic launch
The electric thrust - ionic or plasma - is currently used in several spacecraft and manages to achieve a specific propulsion of several seconds. Atomic thermal launch follows a little further behind. These drive systems are not bad at all to ride around the Solar system, but it would take us about 40.000 years to reach Alpha Centauri.
solar sails
Here we begin to move in an attractive area. A solar sail in the expression of celestial flights. In this sense, this is not a simple candle photonics like the Japanese Ikaros. The adjective 'solar' has a reason. A solar sail is based on a formidable distribution with a representation of parachutes that, like a photonic sail, would use the irradiation coercion of sunlight -and not that of the solar wind as it is sometimes erroneously melted- to hasten the spacecraft to early departure from the Solar System. But to make use of this system it is necessary to extend the adjacent sail of the Sun.
On the other hand, assuming that in the coming decades we are competent to build very light gigantic sails capable of withstanding more than 60 g of promptness and thousands of degrees Celsius, a solar sail could walk up to Alpha Centaur in a thousand or two thousand years. It still happens a lot, but this system can be merged with others to reduce flight time.
Nuclear launch through a series of pulses
Accredited the orion project From the 60s, this system seems crazy, but the truth is that the combined sets of techniques have already been experimented with. A pulsating nuclear ship wiggles around exploding atomic artifacts a short distance from the vehicle. The vehement wave is soaked by a specific plate with spirals, which transfers part of the energy to the ship in such a way that it speeds steadily. Orion was a very promising vehicle for walking around the Solar System, but for space tours this system is not so seductive.
In this order of ideas, the work that is being carried out is really significant because in this way there is greater communication with what would be the distance between alpha centauri and our planet.
Finally, it is important to note that at what distance this alpha centaur from the earth would we have to think about light years as mentioned above, in addition to the fact that there are various classes of dimensions that would have a long time to reach our set of stars closest, to be more precise, about 150 years to reach Alpha Centauri. Not bad for a differential ship, but it doesn't seem to be the most appropriate for a really revealing and meaningful work of automatic belief for those who are dying (not literally speaking) to know the adjacent wonders of our solar system and therefore, of our land.
