English: This image is unique in that it shows both the sizes and distances of the Solar System to scale.
It shows that if the Sun-Neptune distance of the Solar System were scaled down to the 100-yard length of a football field (yellow lines point to goal line to goal line span, roughly 13 meters shorter than a standard soccer, or Association football field), then the Sun and eight planets would be small enough to hold in the palm of a person's hand. The inset shows all 9 objects upclose to just one yard, and this is done to show that typical Solar System depictions are grossly distorted by several orders of magnitude. (To view this image without this inset nor with any markings, click here.) SIZES:
Jupiter along with all the terrestrial planets are located well within the "red zone", to use a term from American football. The exact scale factor is 49,250,000,000-to-1. Precise numbers for the mean orbit distances of the planets as a percent of Neptune's mean distance are (Mercury through Neptune respectively): 1.287%, 2.402%, 3.323%, 5.063%, 17.292%, 31.712%, 63.786%, and 100%. Vertical lines (in white) point to the exact locations where the bodies are found (abbreviating to just the first initial). At the top of each bar is a horizontal line indicating the eccentricity of each orbit, with the 'T' showing the closest and furthest away from the Sun it gets (perihelion and aphelion). At the bottom of each of these are a pair of black lines which likewise show the perihelion and aphelion, but the pair is split to also show how high above and below the field the orbit goes. So this pair of lines simultaneously shows the orbit inclination and eccentricity. This defines a rectangular box that when swept around the Sun forms a "washer" of perfect cylindrical shape within which the orbit of the body will be contained. The orbit of Ceres ("C") has an inclination greater than any planet. And Pluto ("P") has an even bigger inclination, at 15.6° off of the invariable plane (see 3RD DIMENSION section below). Pluto's tilt takes its orbit far below the level of the field with the point indicated near the bottom right of the image, and its orbit goes well above the boundary of this image so is not indicated. Pluto's orbit is located 130 yards away from the Sun, so it's horizontal eccentricity line is a pointer, while showing how the perihelion of Pluto's orbit is actually closer to the Sun than Neptune's.
Distance = Rate x Time The speed of light in a vacuum is a constant rate, so it can be useful for measuring large distances. In the Solar System, here is the time it takes for light from the Sun to reach:[1] Light-distance from Sun —————————————————————————————————————————————— Mercury 193.0 seconds = 3min 13sec ≈ 3¼min Venus 360.0 seconds = 6min Earth 499.0 seconds = 8min 19sec ≈ 8⅓min Mars 759.9 seconds = 12min 39.9sec ≈ 12⅔min Ceres 1381.0 seconds = 23min 1sec ≈ 23min Jupiter 2595.0 seconds = 43min 15sec = 43¼min Saturn 4759.0 seconds = 1hr 19min 19sec ≈ 1⅓hrs Uranus 9575.0 seconds = 2hrs 39min 35sec ≈ 2⅔hrs Neptune 14998.0 seconds = 4hrs 9min 58sec ≈ 4⅙hrs Pluto 19680.0 seconds = 5hrs 28min 0sec ≈ 5½hrs ——————————————————————————————————————————————
——————————————————————————————————————————— Planet Inclination and Scaled Maximum Height Above/Below The Field ——————————————————————————————————————————— Ecliptic Plane Invariable Plane ——————————————————————————————————————————— Mercury 7.01° 6.34° 0.475'=5.703" 0.426'=5.116" ——————————————————————————————————————————— Venus 3.39° 2.19° 0.426'=5.113" 0.275'=3.304" ——————————————————————————————————————————— Earth ---- 1.57° 0 0.273'=3.278" ——————————————————————————————————————————— Mars 1.85° 1.67° 0.490'=5.884" 0.443'=5.312" ——————————————————————————————————————————— Jupiter 1.31° 0.32° 1.186'=14.232" 0.290'=3.477" ——————————————————————————————————————————— Saturn 2.49° 0.93° 4.133'=49.598" 1.544'=18.530" ——————————————————————————————————————————— Uranus 0.77° 1.02° 2.572'=30.859" 3.406'=40.877" ——————————————————————————————————————————— Neptune 1.77° 0.72° 9.266'=111.195" 3.770'=45.238" ——————————————————————————————————————————— The largest excursion of any of the planets is by Neptune, reaching at most 9.266 feet (2.824 meters) above or below the football field (with the field defined as the ecliptic plane). All other planets remain much closer to the common plane. In the invariable plane, the maximum height is again by Neptune reaching up to 3.77 feet (1.15 meters) which is shorter than the height of an average 7-year old child.
