What does 'Clearing the neighbourhood of it's orbit" mean?

In the end stages of planet formation, a planet will have "cleared the neighbourhood" of its own orbital zone, meaning it has become gravitationally dominant, and there are no other bodies of comparable size other than its own satellites or those otherwise under its gravitational influence. A large body which meets the other criteria for a planet but has not cleared its neighbourhood is classified as a dwarf planet. This includes Pluto, which shares its orbital neighbourhood with Kuiper belt objects such as the plutinos. The IAU's definition does not attach specific numbers or equations to this term, but the extent to which all the planets have cleared their neighbourhoods is much greater, by any measure, than that of any dwarf planet or any candidate for dwarf planet known so far.

I love the content of this video but being dyslexic I really hate text videos. >.<

@Arikiel Oh sorry... I did think about reading it out but then I decided I sounded stupid lol, but I do read it out in my dwarf planets video!! xx

where did u get this music from? I like it. it's relaxing lol

[SazzleT400]

@emurray7779311 I found it on my PC. Apparently every PC has this song, however I found it on my PC which is years old. This laptop is new, and doesn't have this song that I can find but it has 3 others. Have a look by going to My Computer > Local Disk C > Users > Public > Public Music > Sample Music. But I can't remember the exact steps to find it on an older PC. xx

@SazzleT400 You wont find it there lol.... It's in C:\Windows\system32\oobe\image­s\title.wma

[SazzleT400]

@Corrupt5358 Heeey that's it! Cheers for that XD x

@phrooster123 um... I KNOW!! You told me that a month ago I've been working so much I haven't had time to put in an annotation to correct it. Calm the hell down why don't you

[SazzleT400]

@rdkitchens Yes it is tidally locked with Uranus, see the links I sent you in private mail. And yes one day on Umbriel is 4.14 earth days long, that's because it takes 4.14 earth days to orbit Uranus. Which obviously at some point it will be on the bright side of Uranus. See the links I have sent you. x

Oh! Pardon me. Now they admit that Neptune is a terrestrial planet and does have a surface. Not too long ago, the scientific community dogmatically stated that Neptune was just another "gas" giant. I suspect they will eventually come to understand that all the other planets have surfaces of some kind maybe hundreds of miles beneath all the apparent gases much like a few miles into the Earth's atmosphere. Former conclusions about Neptune were obviously speculative based upon faulty assumptions.

[Ettenyl56]

Cosmologists often make godlike pronouncements and statements about the outer planets which few people dare to question. If Jupiter, Saturn, Neptune, and Uranus are "gas" giants with no real solid surface, then tell me how did comet Shoemaker Levy crash into Jupiter (a giant ball of gas) leaving a permanent change upon a surface of just gas? How can anything crash into gases and make an observable change upon something that has no solid substance? Will someone please respond?

Miranda = Moon than fall in 3 day in Link!

@MrTeamLeader92 Discovered in 1846 and its orbit is 164.75 earth years long, so it just finished its first orbit since discovery 1.25 years ago. I suppose it depends when you heard it. If you heard it 2 years ago then they would be correct.

[MrTeamLeader92]

i thought neptune hadnt made a complete orbit since it was discovered?

[zechariah14v7]

there are several Kuiper Belt objects that also fit the definition of a dwarf planet, and one particular object is even larger than Pluto, so I'm looking forward to what New Horizons will discover.

[MrIronfist99]

its very umm nice
