- Earth is the third planet of the Sun, so our closest neighbor must be a planet two or four, right? Neither Venus nor Mars is the right answer. Three scientists checked the numbers. In this YouTube video, one of them explains why our closest neighbor is … Mercury!
Muscus has chosen the wrong planet on which to die?
Elon Musk said he wants to die on Mars.
By 2024, Elon Musk wants the land on Mars to land – the billionaire said he himself wants to go to the Red Planet and even wants to die there (just not the impact he laughs at). But did SpaceX choose the wrong planet to colonize? If the plan was to choose the closest planet: yes, really. While Mars is rising in human culture and imagination, most scientific sources call Venus a planet that is the shortest distance from Earth. NASA mentions Venus as our closest neighbor. But while it is true that no other planet is approaching closer – the shortest approach is 0.28 AU (1) or 25 million miles (41 million km) – it is not true that Venus is the closest planet 2) average (although this is also often mistakenly claimed)
Correct line of the solar system
A series of common suspects. Only dimensions are for scale, not for distances. And they usually do not get as well as that.
"As some sort of phenomenon of negligence, ambiguity, or group thinking turns out to be, the propagators of science disseminate information based on a false assumption of the average distance between the planets." writes Tom Stockman, Gabriel Monroe and Samuel Cordner in an article published by Physics Today.
They continue to explain the mathematical method they have developed to prove that when averaged over time, Mercury, the first rock of the Sun, is the closest neighbor on Earth. It also means – mind-blowing – that Mercury is the closest neighbor of all the planets in our solar system including gas giants Jupiter and Saturn and the snowy planets Neptune and Uranus on the frozen outer edges of the system. 19659016] Incredibly cool or unbelievably obvious?

Simulation of Mercury (gray), Venus (orange), Earth (blue) and Mars (red) circling the Sun, and calculating mean distances to Earth.
In Physics Today the three scientists describe their method in great detail. For laity as (probably) you and (of course) me, the YouTube video at the top of this post told by Mr. Stockman is clearer. In 6 minutes and 40 seconds he convinced me.
While some commentators agree ("a fresh new way to think about it!") One or two are annoyed that hog pollo is just moving to this ("Every idiot should is able to indicate this ").
Anyway, one must feel like a commentator who seems to have invented this a long time ago but did not have this video to prove their point: "I told my teacher many years ago that Mercury is closest to Earth, but they laughed at me. "
The video was found here on YouTube . If you like your math as Saturn likes its gravity (spoiler: heavy ), here is the article in Physics Today .

(1) 1 Astronomical unit (AU) is the average distance between Earth and the Sun: 93 million miles (150 million km). Their name derives from the Greek "planetai" for the "wanderers", the planets circling around the Sun, from where the great deviation in the distances between them comes.
