Why was Pluto Not a planet?
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."
How long is a Pluto Day?
6.4 Earth days Pluto's day is 6.4 Earth days long. How long would it take to travel 4 light years? Last year, astronomers raised the possibility that our nearest neighbor, Proxima Centauri, has several potentially habitable exoplanets that could fit the bill. Proxima Centauri is 4.2 light-years from Earth, a distance that would take about 6,300 years to travel using current technology.
How long would it take to get to Pluto at light speed?
4.6 hours Light itself takes 4.6 hours to travel from the Earth to Pluto. If you wanted to send a signal to Pluto, it would take 4.6 hours for your transmission to reach Pluto, and then an additional 4.6 hours for their message to return to us. Let's talk spacecraft.
