Since that's such a large number, let's bring it down toother units of time. So there you have it. It will take youjust over 168 million years to travel 30 light yearsgoing 120 miles per hour.

In this regard, how long would it take humans to travel one Lightyear?

It would take you little under 20,000 years,to travel just 1 lightyear. Let's say that youwant to travel to Kepler 438b, which is over 400lightyears away. If you wanted to travelthere in the fastest spacecraft made by man (New Horizons), itwould take you about 2 million years.

Secondly, how long would it take to travel 39 light years? Voyager 1, Earth's most distant spacecraft, left thesolar system and entered interstellar space in 2012. According toNASA, it is currently speeding away at 38,200 mph. For Voyager 1 totravel 39 lightyears, it would take thespacecraft 685,000 years.

In this way, how long does it take to get a light year?

A lightyear is the distance lighttravels in one year. How far is that? Multiplythe number of seconds in one year by thenumber of miles or kilometers that light travels in onesecond, and there you have it: one lightyear.It's about 5.88 trillion miles (9.5 trillion km).

How long would it take to reach Alpha Centauri?

The journey to Alpha Centauri B orbit wouldtake about 100 years, at an average velocity of approximately13,411 km/s (about 4.5% the speed of light) and another 4.39 yearswould be necessary for the data to reachEarth.

Related Question Answers

Will we ever travel at light speed?

Einstein said it is impossible, but as JenniferOuellette explains some scientists are still trying to break thecosmic speed limit – even if it means bending the lawsof physics. “It is impossible to travel faster thanlight, and certainly not desirable, as one's hat keepsblowing off.”

Will humans ever travel to other galaxies?

According to the current understanding of physics, anobject within space-time cannot exceed the speed of light, whichmeans an attempt to travel to any other galaxy wouldbe a journey of millions of earth years via conventionalflight.

Can we travel a light year?

By the way, light travels at 186,000 miles perSECOND, not per hour. First of all, a lightyear isthe distance light travels in one year. There are 6trillion miles in a lightyear (approximately), sothe distance we need to go is 6 trillion miles /lightyear times 4 light-years, or 24 trillionmiles.

How many Earth years is a Lightyear?

A lightyear is the distance lighttravels in one Earth year. One lightyear isabout 6 trillion miles (9 trillion km). That is a 6 with 12 zerosbehind it!

Is interstellar travel possible?

Because of the vastness of those distances,interstellar travel would require a high percentage of thespeed of light; huge travel time, lasting from decades tomillennia or longer. The speeds required for interstellartravel in a human lifetime far exceed what current methods ofspacecraft propulsion can provide.

How close is the nearest star?

The two main stars are Alpha Centauri A and AlphaCentauri B, which form a binary pair. They are an average of 4.3light-years from Earth. The third star is Proxima Centauri.It is about 4.22 light-years from Earth and is the closeststar other than the sun.

How long would it take to leave our galaxy?

The closest galaxy is the recently discoveredCanis Major dwarf galaxy, which is “only” 25,000 light-yearsaway. So it would take 25,000 years to get there if youtraveled at the speed of light. Actually, that's the amount of timeit would take from the perspective of the outsideworld.

How many light years away is Pluto?

It took 10 years to reach Pluto, andPluto is currently 4.8 billion km from Earth. That's thedistance light covers in a little under four-and-a-halfhours. So at that rate, flying to Kepler-452b would take nearly 28million years.

How big is the universe?

The observable Universe is, of course, muchlarger. According to current thinking it is about 93 billion lightyears in diameter.

How far away is Mars from Earth?

How many galaxies are there?

All in all, Hubble reveals an estimated 100 billiongalaxies in the universe or so, but this number is likely toincrease to about 200 billion as telescope technology in spaceimproves, Livio told Space.com.

Which planet is farthest from Earth?

Pluto: The Farthest Planet (Usually) Pluto, theninth planet in our solar system, was not discovered until1930 and remains a very difficult world to observe because it's sofar away. At an average distance of 2.7 billion miles from theEarth, Pluto is a dim speck of light in even the largest ofour telescopes.

What is the temperature on Pluto?

All planets have temperature changes related totheir seasons; some changes are more extreme than others. At itswarmest, when it is closest to the sun, Pluto can reachtemperatures of minus 369 degrees Fahrenheit (minus 223degrees Celsius). At its coolest, temperatures can fall tominus 387 degrees F (minus 233 C).

How fast does light travel?

The speed of light in a vacuum is 186,282 milesper second (299,792 kilometers per second), and in theory nothingcan travel faster than light. In miles per hour,light speed is, well, a lot: about 670,616,629 mph. If youcould travel at the speed of light, you could goaround the Earth 7.5 times in one second.
