Earth and Uranus are known to be the closest if they are aligned together along with the sun on one side. This cuts the distance between the two planets. If this is the current position of Earth and Uranus, then the distance between them is about 2.57 billion kilometers. It is indeed still a very wide gap, knowing that Uranus is the third to the last planet from the sun; however this is the closest distance these two planets could ever have.
The average dog sleeps for about 12 to 14 hours per 24-hour cycle. Thatâs just the beginning, though. Puppies, who expend a lot of energy exploring and learning may need as much as 18 to 20 hours. Older dogs also tend to need more rest, as do certain breeds.
Time spent napping depends on the dogâs age and personality. Different breeds also seem to have different sleep requirements. Large breeds, such as mastiffs and Saint Bernards, generally spend a lot of time sleeping â up to 18 hours a day. True, dogs do sleep more than humans, but they donât sleep as soundly as we do. When they sleep and how much they sleep depends on the level of activity in their lives.
