Revealing video of a former NASA worker shows the size of each planet in the Solar System compared to Earth


Many of the wonders we see of the Solar System and the depths of space shown by the POT They are illustrations. Some are imperceptible to the naked human eye and are obtained through the breakdown of mathematical and physical data.

Others, like that of the worlds of our Solar system they are visible but difficult to represent on a real scale, due to the magnitude of the objects that transit around the Sun.

However, the impressive work of scientists at the POT and other space agencies are responsible for making us understand with simple examples, what for them as a scientific community they had to decipher through equations and formulas.

It is impossible for us to stop in a line, side by side, to the eight planets and the Sun to be able to determine the differences in sizes on a real scale. And it would be even more complicated to see them together to measure the speed at which each rotates on its own axis.

The illustration of the former NASA worker

So, with the intention that we all understand these processes that occur in our stellar region, the work of the Dr James O’Donoghueaccording to Xataka, a British scientist who worked for NASA and who currently works at the JAXA (japan space agency).

The representation seems simple, but Dr. O’Donoghue reflected the almost 143 thousand kilometers that Jupiter measures, with the 12,756 kilometers of the Earth, the 4,880 of Mercury and the surprising magnitude of the Sun.

This makes it clear to us how small we are in the face of existence and how much we still have to discover.

The speed at which the planets rotate

The fastest planets to complete a single day, coincidentally, are the giants of the Solar System: Jupiter and Saturn.

The gas giant has a very slight tilt of 3.1 degrees and completes one revolution on its own axis in just 9 hours and 55 minutes. While the special owner of the ring of dust and rocks, it takes to rotate completely a few 10 hours and 33 minutes. Saturn it has the peculiarity of slightly surpassing Mars and Earth in inclination: 26.7 degrees.

Within the fast ones we must mention the dwarf Ceres, of which it is still debated if it can be considered as a planet or an extremely giant asteroid. In either case, this rocky body rotates in 9 hours and 4 minutes, with only 4 degrees of tilt.

Uranus, Neptune Y Mercury they have very different rotations and tilts, but the first two have very similar rotation times.

Mercury it is the slowest of all and its inclination is practically nil: 0.03º. The complete return is given in 58 days and 15 and a half hours. While Neptunelooking almost the same as Earth at 28.3 degrees, completes its revolution in 16 hours.

In the case of Uranusits inclination is opposite to that of our world (97.8º) and it finishes turning on its axis in 17 hours and 14 minutes.

Lastly, there is our friend Pluto, which ceased to be considered a planet in 2006. Its inclination is 122.5 degrees in the time zone and it completes its return in 6 days, 9 hours and 18 minutes.
