A Mercury, Venus, Earth & Moon (Luna), Mars & Saturn Orrery. This one is different than my previous Orrery models, where instead of an animated gif for the earth/moon, I am using mathematical expressions to calculate the moon's orbit around the earth, and the size of the moon as it goes in/out of the foreground. As far as i can see, none of the other solar system models in Facer use this technique. Basically, it calculates an orbit, around an orbit, and then it calculates the size of the moon as it goes around the 2nd orbit. Plus I added Mars & Saturn. -Mercury, Venus, Earth, Mars & Saturn orbit the sun. The Earth spins, at 23.4 degrees to the orbital plane. Earth's year orbits the sun once every 15 seconds. Mercury's year is accurate relative to a realistic 1/4 of the Earth's year, Venus's year is accurate to a realistic 5/8 of an Earth year, Mars's year is accurate to 1.89x Earth's year, and Saturn's year is accurate to 12x Earth's year. Earth's Moon, Luna, is orbiting the Earth as well. Orbital scaling is off, to make the model more visually appealing. -Current Weather Condition, which is day/night aware is bottom left, with current temperature. -Watch battery level dial window is on the left. Green if level is above 60%. Yellow if level is between 30 and 60%. Red if level is below 30%. Colour coded digital readout. -Steps dial window is on the right. Red if amount walked is less than 3000 steps. Green if amount walked is over 6000 steps. Yellow in the middle. Progress from left to right. Colour coded digital readout to nearest 0.1k steps. -Current moon phase is on the bottom right. -Date is by the moon phase at the bottom right. -OLED, AOD mode, 12 hour mode, 24 hour mode compatible. Note: There is a bug in the android phone preview. It works fine on the watch and in the web browser preview. Updated April 28 2021: Slowed down the moon orbit.
