72 hours is one day
The distance of Pluto doesn't matter, since the orbit would be the same no matter how fast Pluto travels.The orbit of Pluto is about 22,698,700,000 miles long. if Pluto traveled that distance at 62500 miles per second, it would take 363179.2 seconds or about 100 hours to orbit the Sun.

For a long times, it was considered to be VY Canis Majoris, but new studies have reduced its size. The present record is held by UY Scuti at 1708 times the diameter of the Sun. That works out to about 2,250,000,000km.

17398390800/186000= approx 25.983 light hours
Who knows? In all probability, it probably has, but as it is about 4,900 light years from us, it will take that long for it's demise to reach us.
If, for any reason, earth were to touch the star, it is possible it would be just torn apart by the eddies and curves of the plasma and other phenomena. The surface of the star is not that hot (only 3000K) and it might not melt all of earth. Instead, what was left of earth could enter the star because of it's massive gravitational pull and, if it got deep enough, then be completely vaporized by the truly high temperatures further in. there is the off chance earth's remains would simply be thrown away, pushed by the solar wind, but I know of no scientific conclusion that may decide either way. Just as a reminder: if this star is in our galaxy, which it is, and it creates a hyper-nova, which it will, the gamma ray burst could be strong enough to kill every single living organism in the entire galaxy. It all depends on the mass of this particular hyper-star. They have been detected in other galaxies where the existing hyper-novas are so strong, satellites here can read them as clearly as they would read a nuclear test on earth. or VY Canis Majoris.. would completely annihilate earth, if it were to actually collide with it. It would be as if you stepped on a pollen particle on the sidewalk. But VY Canis Majoris colliding with earth is impossible. COMPLETELY IMPOSSIBLE. Even if went supernova or hyper nova it wouldn't hurt us or our solar system. and Note: If thrown at VY Canis Majora, earth would never reach any where near the star. At a long distance, earth would be vaporized and expelled as stardust by the solar wind.
The diameter of VY Canis Majoris is Est. 3,063,500,000 km. (but disputed) If the Sun was replaced by VY Canis Majoris, its surface would extend to the orbit of Saturn. Assuming the upper size limit of 2100 solar radii, light would take more than 8 hours to travel around the star's circumference, as opposed to 14.5 seconds for our Sun. It would take over 7,000,000,000,000,000 (7 Quadrillion) Earths or 7,000,000,000 (7 Billion) Suns to fill VY Canis Majoris. [See Link]
The fleet of American space shuttle craft will no longer orbit the Earth. I don't know how long it would take to orbit the Moon.
the answer would be 14 by 6
5 hours
it would take 88 earth days to orbit the sun so it is 1/4 earth years.
