  • The cool thing is that Saturn is the Roman name for Cronus (the Greek Titan) and the planet has moons like Titan and Tethys and Rhea and Iapetus (those three Greek Titans also) and many others.

  • I have always found it strange for the size of earth's moon is compared to planet to moon ratio of the rest of the solar system planets . Anyone have a theory on that ?

  • @tanarus77 To me its just chance...in the early days of Solar System creations it is said there were about 100 planets. then most of them collided with each other, creating our planets and thier moons...the gaseous planets are giants but their moons too, some of them bigger than Planet Mercury, but the ratio to the parent planet is smaller than that of Earth - Moon System. BTW Pluto - Charon is just like Earth - Moon, with higher ratio. but who knows maybe there are more than chance to it !

  • @KurdstanPlanetarium thanks for you response. Can you imagine how big a moon of jupiter would be if it had one like earth that was 1/80th its size

  • @tanarus77 Nice point, when we talk a bout King of the Planets Jupiter, we talk about huge size. just imagine Jupiter itself 384 times bigger than Earth, i.e you can have 384 Earth like planets inside Jupiter, so if we to imagine a Moon with size 1/80th of Jupiter than we talk about a Moon nearly 5 times bigger than Earth.

    what a fascinating world would be.

    BTW you know the Great Red Spot a Hurriacan more than 300 years raging since we know it, it is 3 times the size of Earth, just imagine!

  • @KurdstanPlanetarium Is mars really a baron desert red planet IYO?

  • @MadeInOregon27 Mars certainy a desert but I wouldn't call it baron, I do belive in existing of live on Mars, not higher form of live but microbic bacteria !!!

  • @tanarus77 Great question! I favour the Biblical ideology, just to add to your observation that the suns size and distance from the earth, compared to the moons size and distance from the earth, give us the exact same size bodys- from our perspective, which seems like an improbable 'fluke'. Angular momentum would suggest the planets would spin slower than the sun, they dont, and that the outer planets should be smaller than the inner, they're not. Lol, its a funny world we live in. :o)

  • Tarda en completar una vuelta alrededor de Saturno 79,33 días, a una distancia media de 3.561.300 km.

    Uno de los hemisferios del satélite es mucho más oscuro que el otro, peculiar característica que se podría deber a la una composición distinta del material de la superficie, proveniente del interior de la propia luna o bien de materia de otros satélites o anillos: no se conoce con certeza el motivo real, aunque la segunda hipótesis cada vez es más apoyada por evidencias observacionales.

  • Jápeto (Iapetus) es uno de los satélites más raros del planeta Saturno; es el octavo más distante al planeta y el tercero en tamaño, con un diámetro de alrededor de 1.500 km, después de los satélites más grandes Titán y Rea. Fue descubierto por Giovanni Cassini en 1671.

  • LOL FAKE Just kidding. This is cool :)

  • Goodness i see what you mean about it having a Bright half and a dim half, this is visually observable in you graphics. Quite a lot of moons get tidally locked to the parent planet.

    Is this a gravitaional relationship with distance or evidence that the moon was captured by the planet?

    Our Moon is Tidally locked to earth for example, isnt it?

  • yea and certainly most satellites of the planets inculding our moon are synchronous i.e tidally locked, due to tidal gravitational forces with its parent planet over time..this suggest that Iapetus was there too for a very long time, and certanily with a diameter of 1495 Km it really is a big moon rather than captured asteroid..

  • The Earths moon and Tidal Locking

    Is the earth moon synchronous relationship due to the effects that the oceans has on the orbiting moon?

    What therefore is cauing this relationship on saturn, large amounts of Gas?

    I remember reading somewhere that this tidal relationship can cause the core of the moon to heat, causing volcanic mantle/crust ruptures, is this true?

    Is the moon Lapetus to small for this?

    p.s. wasnt there a space probe called cassini? was this named after this astronomer?

  • The ocean cause Earth Rotation to slow down, but the reason for tidal lock, is the gravitational of Earth on the lunar land and that caused it to slow its rotation and make it face Earth permanantly,the same force acting on other satellites of the outer planets, and remember they are giant..for example Io (Jupiter's moon) surface rises up and down 8 meters a day and that causes heating up Io's interior and so is a volcanic moon, as you said. yes,cassini was named after Astronomer G.D, Cassini.

  • So cassini was just before the rev. James Bradley he was 1692-1762, my grandfather enjoyed astronomy and created alot of stamps you see.

  • Giovanni Domenico Cassini (June 8, 1625September 14, 1712) was an Italian/French mathematician, astronomer, engineer, and astrologer. Cassini, also known as Giandomenico Cassini or Jean-Dominique Cassini, was born in Perinaldo, near Sanremo, at that time in the Republic of Genova. so that makes him older than James Bradly.

  • Ah i had it the wrong way round then!!

  • Just to add. here on Earth we know about Ocean tides and so the word tidal lock though has similar name and effect i.e rising up and down of a mass body of water , but remember even here on Earth the land has a tide of about (1") and we hardly feel it as its so small amout, but on a moon such as (Io) the land rises up and down 8 meters a day which is more than tidal waves of River Thames here in London UK. Tidal lock is the effect that caused by gravitational tidal forces of body on another.
