"Although New Horizons was the fastest spacecraft ever launched, it still took it nine and a half years".
It is one of the fastest spacecraft ever launched from Earth, travelling at a speed of 14.5km a second or 52,000km an hour.
Its voyage began in January 2006, and it became the fastest spacecraft ever when it was boosted at more than 16.2km per second to cross the Moon's orbit within nine hours.
Even for our fastest spacecraft, it would take about seventy thousand years to reach Alpha Centauri B, and the planet, which orbits its sun in about three days, likely has a surface temperature of around two thousand degrees.

However, it would take today's fastest spacecraft 30,000 years to accomplish the same feat.
The fastest spacecraft so far launched into space, the NASA-Germany Helios probes, traveled at 250,000 kilometers per hour.
As is the case in Fig. 1, the faster spacecraft receives a larger flux of impact plasma ions, resulting in a stronger reduction of the spacecraft potential.
The fastest spacecraft ever launched, it will fly past Pluto and its moons in July 2015 before heading deeper into the Kuiper Belt.
On the way it will hit a top speed of 430,000 miles per hour, which will make it the fastest spacecraft ever launched.
