Life on earth is possible due to presence of sun. It is a perfect sphere of hot plasma. It is but natural that one expects Sun to be fundamentally the same, if viewed from the surface of other planets, after all, all planets are orbiting the same star. However since our Solar System is so immense, the Sun changes in appearance. Illustrations and models of the Solar System pack the planets conveniently together so that we can see the planetary order, but Mars’ orbit averages at 1.5-times further from the Sun than ours, by around an extra 75 million kilometres (46.6 million miles). Then, Jupiter is five-times away from the Sun, Saturn is 9.5-times, Uranus 19-times, Neptune 30-times, and Pluto is 39-times further away respectively. Viewing from the surface of the each planet, we would see the Sun in a different way.
So near the Sun and with little climate, Mercury sees the Sun as a splendid white ball ruling the sky at 2.5-times the size that we’re used to. Mercury is 2.5-times nearer to the Sun than Earth. With a very thin atmosphere mercury’s average temperature is around 400 degrees Celsius (752 degrees Fahrenheit). Here, the Sun seems 2.5-times bigger as a splendid white ball ruling the sky – and makes the surface terribly hot and brilliant.
Venus’ circle is the nearest to Earth’s at 72 percent the size, so here the Sun would seem only somewhat bigger than in Earth’s skies – however most daylight never achieves the surface because of its continuous cover of acidic clouds.
On Mars, our different rovers have caught many pictures of the sky, including orange daytime skies and blue-tinged nightfall’s. This is because of the diverse blend of gas and dust on Mars contrasted with that of Earth. The Sun looks around 37 % smaller as compared to its size from earth, and provides lighting that compares to a cloudy afternoon here on Earth.
As Jupiter has no surface, we are probably not going to get pictures from inside its environment at any point in the near future, yet the Sun here seems just a fifth of the size and, given the blend of gasses, the sky is thought to appear as dark blue.
In Saturn the Sun is about half the size, but still visible as a disc. Although sun is around 1000 times dimmer in Saturn (as compared to Earth) still it is bright enough to gaze from naked eye.
Moving out to Uranus, the Sun is beginning to achieve the breaking point at which our eyes would have the capacity to determine it as a circle, and from Neptune and Pluto, the Sun shows up as a bright point of light. Indeed, even now so-called dwarf planet Pluto, where the Sun is a star among stars, it would in any case be around 250-times brighter than the full Moon and difficult to look at.
It is amazing to consider that, even inside the planets of our Solar System, the Sun can look so different; but also a graphic demonstration of its power, since it remains so splendid, even at 5.9 billion kilometers away.
