Use planetary orbits and scale ratios to draw scale solar system orbits while exploring gravitational forces.

Get your scrolling hand ready. An interactive web page has created a scale model of the solar system, where the moon is the size of just one pixel.

Normally, what textbooks do is to show two separate scales. One scale showing the orbits of the planets and another scale showing the size of the planets. Unfortunately, this way you don't get a ...

Solar System distances to scale, showing the newly discovered 2018 AG37, nicknamed "Farfarout," compared to other known Solar System objects, including the previous record holder 2018 VG18 "Farout ...

If you’ve ever seen an illustration of the solar system, the odds are good that it was wrong. Not that it messed up the order of the planets, but that the scale was completely off. "Every single ...

Solar system distances to scale, showing the newly discovered planetoid, nicknamed "Farfarout," compared to other known solar system objects, including the previous record holder 2018 VG18 "Farout ...

Uncover the true scale of our cosmic neighborhood, exploring the distances between the Sun, the planets, and the far reaches of the Solar System.We begin with a deep dive into the Earth's position ...

Students could calculate the distances and sizes of the planets in the solar system based on the Sun being the size of a football.

An illustration of the scale of our solar system. Distances here are measured in astronomical units (AU). (Credit: NASA) Click on an article about space on Discover, and you’ll likely run into a ...

So astronomers devised the astronomical unit (AU; see “Solar system yardstick,” p. 26) as a simpler way to express distances at the scale of planetary orbits.
