How many feet away is the nearest star?
How many feet away is the nearest star?
The Closest Star If the Earth were scaled to 0.5 mm diameter, then the Sun would be a ball of diameter 5.4 cm ( a little smaller than a tennis ball) at a distance of 5.9 m (19 ft). On this scale, Alpha Centauri would be 1.48 x 106 meters or about 890 miles away.
How long would it take to get to nearest star?
In short, at a maximum velocity of 56,000 km/h, Deep Space 1 would take over 81,000 years to traverse the 4.24 light-years between Earth and Proxima Centauri. To put that time-scale into perspective, that would be over 2,700 human generations.
How far is the next star from Earth?
The closest star to Earth is a triple-star system called Alpha Centauri. The two main stars are Alpha Centauri A and Alpha Centauri B, which form a binary pair. They are about 4.35 light-years from Earth, according to NASA (opens in new tab).
How far away is Proxima?

How long would it take to get to Alpha Centauri at Warp 9?
52.07 hours
Star Trek: The Original Series
| Warp factor | Calculated speed (c) | Travel time from Earth to Alpha Centauri |

| 8 | 512 | 3.09 days |
| 9 | 729 | 52.07 hours |
| 10 | 1000 | 37.96 hours |

How long would it take to travel 4.2 light-years?
about 6,300 years
Proxima Centauri is 4.2 light-years from Earth, a distance that would take about 6,300 years to travel using current technology.
Will humans ever reach another star?
The nearest star is four light years away. That means that light, traveling at 300,000 kilometers per second would still need FOUR YEARS to reach the nearest star. The fastest spacecraft ever launched by humans would need tens of thousands of years to make that trip.
Can you land on a star?
The calculations show that, even using the most theoretical of technologies, reaching the nearest star in a human lifetime is nearly impossible.
What distance is 1 light-year closest to?
approximately 6 trillion miles
A light-year is the distance a beam of light travels in a single Earth year, which equates to approximately 6 trillion miles (9.7 trillion kilometers).
What is 1 light year away?
about 5.9 trillion miles
A light-year is the distance light travels in one year. How far is that? Multiply the number of seconds in one year by the number of miles or kilometers that light travels in one second, and there you have it: one light-year. It’s about 5.9 trillion miles (9.5 trillion km).
How far is Vulcan from Earth?
The Real Vulcan: This system is some 16 light-years from Earth, which is about 94 trillion miles (151 trillion km) away. Unfortunately, it would take us nearly 81,000 years to reach the *closest* star.
Will humans ever travel at the speed of light?
So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no.
Has anyone been to the Sun?
No. Outside mythology, no human has ever attempted to travel to the Sun. The main reason is fairly obvious—it’s too hot. Even in a well-protected spacecraft, you could only get within about 2 million kilometres (1,300,000 mi) before burning up.
How many Earth years is a Lightyear?
In a vacuum, light also travels at speed of 670,616,629 mph (1,079,252,849 km/h). In one Earth year of 364.25 days (8,766 hours), light travels a distance of 5,878,625,370,000 miles (9.5 trillion km). This distance is referred to as one light year.
What is inside a black hole?
The singularity at the center of a black hole is the ultimate no man’s land: a place where matter is compressed down to an infinitely tiny point, and all conceptions of time and space completely break down. And it doesn’t really exist.
