📄𝗧𝗿𝗮𝗻𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻:
If we observe the planet Mars in the sky over a period of 2 years, we see that it slows down, stops, goes back and then returns its original path.
Why does Mars move like that? In reality, Mars doesn’t actually slow down or stop or go back. The movement in the sky we see is just an illusion called apparent retrograde motion. It happens because Mars orbits the Sun at different distances and speeds than Earth does.
If we look at the solar system, planets that are closer to the Sun orbit faster. As you know, Earth orbits the Sun every 365 days. Mars, on the other hand, completes one orbit of the Sun in 687 days - almost twice as long. That means every 2 years Earth catches and passes Mars. If we look at Mars and Earth’s orbital movements from Earth’s perspective, we can see clearly that when Earth catches and passes Mars, Mars’ path looks like a loop.
Apparent retrograde motion is valid for other planets, including the inner planets Mercury and Venus. However Mercury and Venus always pass Earth during daytime, so their apparent retrograde motions are difficult to observe.

that's just....the best explanation of retrograde I've ever heard and seen. Thank you!
Sadly it isn’t what is occuring.
@@currencyprofits what is occurring?
@@KimSooAcu First of all, everything which is being stated correct assuming that the model shown was accurate. Now think about our Orbit around the sun, depending on our Orbit, we get the 4 seasons. There is a part of Earth’s Orbit, since all motion is uniformed, where it passes closer to the sun, that allows us to observe the sun Much bigger and hotter in the sky for several months, yet, we can’t see that in this model. Thus making everything total BS.
@@currencyprofits Do I understand correctly that you do not like the orbits being drawn circular rather than elliptical? And second, is the "Apparent retrograde" actually happening, according to you?
@@currencyprofits Dude, that isn't the cause of the seasons. The axial tilt is the cause of the seasons.
There are so many astronomy youtubers and yet no one thought of explaining this.
I learnt about this from an Indian astrologer and his presentation on pc app drawing and saw today animation explanation.
Thanks.
Wonderfully made and narrated
Excellent, thank you!
I remember learning this years ago in school, but an animation is much easier to understand than a diagram in a book.
May I please know what grade and what school you attended when you were taught about astrology. We have never been taught this when I was in school. Ever.
@@tumelotshepeI was in the 4th grade at Mudgee public school when we learnt about the solar system, as for learning about retrograde orbits, that would have been from an astronomy book in the school library.
@@tumelotshepeI learned this in 8th

I’ve been searching everywhere for this bless up
I always liked how the Ptolemaic system explained the retrograde motion of the planets. It made 100% sense!
This is such an awesome channel!!!
It looks so great and mesmerizing 😮
Great explanation
great vid
Thanks!
Great scientific explanation sans astrology, thanks
I think a horizontal demonstration from the same plane would show better than this overhead view.
It works to point out the different speeds from the overhead view but you have to transition to the horizontal plane and show why the earth orbit in relationship to mars causes the back & forth you witness from your observation on the ground.
great video
It is not at all accurate so what makes it great?
Tq
That's actually cool. It looks at they're doing a little dance around the sun :D
So you change the planet yr looking for progressing in the same motion . eg Neptune . . Thank you for this .
Come for the science, stay for the music.
earth will be next right?
So that's how one of the final signs of the day of judgement happens.
"always pass earth DURING THE DAYTIME"??? Did you really mean "when they are very close to the sun"?
Mercury and venus have a much smaller radius compared to earth. So seeing from earth these planets always remain within 30 degrees from the sun. So it always occurs in the daytime and we can't see the event
@@sabarishp9945thank you!
In other words, during day time the half of earth facing the sun is exposed to thr inner orbits which have mercury and venus and the other half of earth during it's night time will face outer orbits and their planets

So, i guess that's how one of the final signs of the day of judgement happens.
No.
Unfortunately, this explanation for the observed retrogradations of Mars does not stand up to close scrutiny. Mars is actually observed to retrograde for less time (61 days) and width during its CLOSEST passages to Earth (approx. 0.37AU) - and for more time (83 days) and width during its FURTHEST passages to Earth (approx. 0.67AU). This is contrary to the most basic laws of perspective - as thoroughly expounded and illustrated in my book "The TYCHOS - Our Geoaxial Binary System" (2022).

Horrible video as that isn’t the orbit the Earth takes around the Sun. Lol. In Summer, we are closer to the sun in Orbit than we are in Winter lmaooooooooo😅😅😅😅😅😅😅
Who's "we"?
Buddy , pls dont tell me you think seasons happens because of earth and sun's distance...It's cause of earth's tilt with its axis. Earth is actually farthest from the sun in July.
