View Available Hint(s) Suppose the planet Uranus were much brighter in the sky, so that it was as easily visible to the naked eye as Jupiter or Saturn. Which one of the following statements would most likely be true in that case?
A. Its slow motion through the sky would have led it to be named after the Goddess of Procrastination.
B. Its gravity would cause the tides to be much higher than they actually are.
C. The discovery that the Earth is a planet going around the Sun would have come hundreds of years earlier.
D. A week would have 8 days instead of 7.
E. Its brightness would make it possible to read by starlight at night.

Answer 1

The answer to the question: Which one of the following statements would most likely be true in that case?, the case being that Uranus became much brighter in the sky, so that it was easily visible to the naked eye, just as Jupiter and Saturn, are, would be, D: A week would have 8 days instead of 7.

Step-by-step explanation:

The reason comes from the size of the planets, the speed of rotation of both the Earth and the planets, and also their proximity to Earth. All of these factors influence how well the naked eye can see a planet from Earth. In the case of planets as enormous as Jupiter, they are easily seen in the night sky, with the naked eye, because of their large diameter. So, regardless of their distance from Earth, and any other factors, their large size permits us to see them without the use of binoculars, or a telescope. But Uranus, though still larger than Earth, and visible to the naked eye for someone who knows what to look for, and where, is still seen as just a tiny speck. If this planet suddenly became much more visible in the night sky, without the need of a telescope its because the Earth´s time of rotation has increased the exposure to Uranus, and thus mean that we would have an 8-day week, instead of the norma 7-day one.
