The photosphere is more or less the Sun’s visible surface and stretches up to 400km. The chromosphere is a low-density region that reaches up to 2,000 km above the surface where we find the Sun’s flickering spicules. The corona is the vast outermost region of the Sun’s atmosphere which, like the chromosphere, is only visible when the Sun is blocked out by the Moon during total solar eclipses. The corona appears as streams of ionized gas reaching millions of kilometers out into space.

Earth is at the Sun’s 9 o’clock and Jupiter is at the Sun’s 12 o’clock. Both are traveling counterclockwise but Earth is traveling much faster. In the time Earth travels all the way around and back to 9 o’clock, Jupiter will only travel one hour on the clock, from 12 to 11. For simplicity’s sake, let’s lock Jupiter to the 12 o’clock position. https://images.squarespace-cdn.com/content/v1/66796ff00cca0f1155485fd9/55453354-7d3c-47fe-a247-552542319752/IMG_9493.jpg Astro Blog - Why do planets sometimes move backwards? - As Earth begins to travel around the Sun, Jupiter appears to move from right to left against the background stars. Pay attention to how the red arrow changes direction as Earth’s orientation to Jupiter shifts. https://images.squarespace-cdn.com/content/v1/66796ff00cca0f1155485fd9/3db52083-2751-4eaf-bed0-61cb53726355/IMG_9494.jpg Astro Blog - Why do planets sometimes move backwards? - Earth continues on to 6 o’clock where the Sun at the center lies between the two planets. We perceive this on Earth as Jupiter getting closer and closer to the Sun each evening until it disappears into the glare of daylight. Jupiter’s closest pass to the Sun is known as a solar conjunction. https://images.squarespace-cdn.com/content/v1/66796ff00cca0f1155485fd9/9f871f9a-1481-4592-9b39-e4e2d9bccf1f/IMG_9495.jpg Astro Blog - Why do planets sometimes move backwards? - Earth continues past 6 o’clock as Jupiter emerges from the other side of the Sun, still moving from right to left against the background stars but now visible in the morning sky. https://images.squarespace-cdn.com/content/v1/66796ff00cca0f1155485fd9/836a1085-ad86-4ed7-88f6-8d345757a5aa/IMG_9497.jpg Astro Blog - Why do planets sometimes move backwards? - Once Earth reaches 3 o’clock, Jupiter’s right to left motion will appear to stop. By this point, Earth’s angle of motion in its orbit is now sending it towards Jupiter. https://images.squarespace-cdn.com/content/v1/66796ff00cca0f1155485fd9/cc1b0fa5-47a5-4aba-b9cf-460e02316044/IMG_9498.jpg Astro Blog - Why do planets sometimes move backwards? - Remember that both planets are still moving counterclockwise, but as said before, Earth is moving faster. Earth is now coming up behind Jupiter and will gradually close the distance. As Earth catches up to Jupiter, the gas giant’s slower counterclockwise motion not only appears to stop but will actually begin moving backwards (this time from left to right against the background stars). This is the retrograde motion we’ve been looking for. A good analogy to explain this effect would be you and another car driving parallel on a highway. If you are driving faster, the other car will appear to move backwards even though you both are moving the same direction. https://images.squarespace-cdn.com/content/v1/66796ff00cca0f1155485fd9/44f92083-cdba-48a9-925b-f8b98cbc2153/IMG_9499.jpg Astro Blog - Why do planets sometimes move backwards? - Earth eventually has caught up to Jupiter in its orbit, putting it on the opposite side of Earth as the Sun. This is orientation is known as opposition. It is here that the speed of Jupiter’s retrograde motion is most pronounced because they are closest to each other and Earth’s angle of motion relative to Jupiter is most parallel. https://images.squarespace-cdn.com/content/v1/66796ff00cca0f1155485fd9/27e9d412-7bef-4317-914b-32e0d5a3e3f1/IMG_9500.jpg Astro Blog - Why do planets sometimes move backwards? - Upon passing opposition, Earth will continue to pull ahead of Jupiter, but the gas giant’s retrograde motion will begin to slow as Earth's orbit changes the angle with which it moves relative to Jupiter. This time, Earth is moving away from the gas giant. https://images.squarespace-cdn.com/content/v1/66796ff00cca0f1155485fd9/06bb4967-ce61-47e7-aa19-70d913686c5f/IMG_9502.jpg Astro Blog - Why do planets sometimes move backwards? - When Earth finally comes back around to its original 9 o’clock position, Jupiter’s retrograde motion comes to a stop. The gas giant will again resume its normal prograde motion as Earth continues back around the far side of the Sun once again to repeat the process over. Now, if we hadn't locked Jupiter to the 12 o’clock position it would have made it to the 11 o’clock position upon Earth completing a full orbit back to the 9 o’clock position. Honestly, the only difference here would be that Earth would have to reach further around its orbit to hit all of the previously mentioned steps. https://images.squarespace-cdn.com/content/v1/66796ff00cca0f1155485fd9/108c43c1-2427-48c9-9cc9-7735d22d9bf8/IMG_2346.jpg Astro Blog - Why do planets sometimes move backwards? - We see this same pattern of prograde and retrograde motions among all of the superior planets. However, the further away the planet is, the less pronounced the retrograde motion appears in terms of both speed and angular distance. https://images.squarespace-cdn.com/content/v1/66796ff00cca0f1155485fd9/56f3d74d-57ec-4627-b06f-65cf358a0ab3/IMG_9614.jpg Astro Blog - Why do planets sometimes move backwards? - Notice the more extreme difference in the two angles for the closer planet, Jupiter, than for Saturn. https://harfordastro.org/blog-4-1/the-final-experiment monthly 0.5 2025-05-18 https://images.squarespace-cdn.com/content/v1/66796ff00cca0f1155485fd9/60741da7-f8b5-4f33-ac5b-f029657837cb/GMP_U2F2ZUdIMD Astro Blog - The Final Experiment (Updated) - Make it stand out Summer in the southern hemisphere sees the south pole tilted directly towards the Sun, bathing Antarctica in constant daylight.

As Uranus catches up to Neptune in its orbit, Neptune's gravity pulls it along and makes it move faster. Once Uranus passes Neptune, it starts to move away from it and Neptune's gravity continues to pull back on it, slowing Uranus down. The purple arrow extending from Uranus represents the strength and direction of pull that Neptune's gravity has on Uranus' trajectory.

Different parts of Earth are pulled with different amounts of strength. https://images.squarespace-cdn.com/content/v1/66796ff00cca0f1155485fd9/a8fd7d9e-6313-49f6-b56f-122fb7325200/IMG_6556.jpg Astro Blog - Why do planets have rings? - Make it stand out This graph shows the scaling of the strength of gravity with distance. The vertical numbers represent the strength of gravity as a fraction of the original gravity (1). The horizontal numbers represent the distance from the object as a factor of the original distance (For example, 4 equals 4 times the original distance). https://images.squarespace-cdn.com/content/v1/66796ff00cca0f1155485fd9/f8ac4801-224f-4ee3-857b-9118c876ecdf/IMG_1476.jpg Astro Blog - Why do planets have rings? - Make it stand out As a moon gets close enough to the planet, the gravitational pull shoots up dramatically. Keep in mind that the moons are large and thus their bodies encompass a greater amount of difference in tidal force than an object that is only a kilometer across. Both the size and density of the moon are important factors to where the Roche limit lies. https://images.squarespace-cdn.com/content/v1/66796ff00cca0f1155485fd9/77cce97a-b1c1-4ab2-a227-a31d7b2ff4f9/IMG_6600.png Astro Blog - Why do planets have rings? - Make it stand out Saturn has 13 very reflective rings made up of trillions of chunks of ice. There are also numerous small moons that glide around and in between rings that act as gravitational "shepherds" that maintain the ring's shape.
