Not only that, is Pluto a Lightyear away?
1 A.U. is the average distance between the Sun and the Earth, which is about 8.3 light minutes. So Pluto is approximately 33.8⋅8.3≈280 light minutes away.
Just the same, how long would it take to drive from the sun to Pluto? Luckily, at a Boeing 777's maximum velocity of 590 miles per hour, the trip to Pluto will take only about 680 years.
Ergo, will we ever travel at light speed?
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. ... So, light-speed travel and faster-than-light travel are physical impossibilities, especially for anything with mass, such as spacecraft and humans.
How fast can we travel a light year?

It took 10 years to reach Pluto, and Pluto is currently 4.8 billion km from Earth. That's the distance light covers in a little under four-and-a-half hours.
From an average distance of 3.7 billion miles (5.9 billion kilometers), Pluto is 39 astronomical units away from the sun. One astronomical unit (abbreviated as AU), is the distance from the sun to Earth. From this distance, it takes sunlight 5.5 hours to travel from the sun to Pluto.
Pluto orbits about 3 billion miles (4.8 billion kilometers) from the sun on average — very far away, but not so distant that the dwarf planet is immersed in continuous darkness. To an observer on Pluto's surface, the sun would be about 1,000 times dimmer than it is here on Earth, NASA officials said.
At a minimum the distance between Earth and Pluto are 29 astronomical unit . An AU is defined as 149597870700 meters. If you are a halfway average walker, you will make about 6 kilometers an hour, which means it will take you 24932978,45 hours or approximately 2844,28 years to walk to Pluto.
“There is no real practical limit to how fast we can travel, other than the speed of light,” says Bray. Light zips along at about a billion kilometres per hour. ... Therefore, humans should – in theory – be able to travel at rates just short of the “Universe's speed limit”: the speed of light.
Laser beams travel at the speed of light, more than 670 million miles
per hour, making them the fastest thing in the universe
For one thing, while nothing has ever been observed travelling faster than light, that does not mean it is not theoretically possible to break this speed limit in very special circumstances. ... There are galaxies in the Universe moving away from one another at a velocity greater than the speed of light.
Intergalactic travel for humans is therefore possible, in theory, from the point of view of the traveler. ... Traveling to the Andromeda Galaxy, 2.54 million light years away, would take 28 years on-ship time with a constant acceleration of 1g and a deceleration of 1g after reaching half way, to be able to stop.

For most space objects, we use light-years to describe their distance. A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km). That is a 6 with 12 zeros behind it!
Answer. The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”
