Topic: Plutino


  
  Dave Jewitt: Plutinos
By extrapolating from the limited area of the sky so far examined, we have estimated that the number of Plutinos larger than 100 km diameter is 1400, to within a factor of a few, corresponding to a few % of the total.
First, the Plutinos are observationally over-assessed due to their being closer (brighter), on average, than the Classical KBOs giving rise to an observational bias in favor of the Plutinos.
Pluto is distinguished from the Plutinos by its size: it is the largest object identified to date in the 3:2 resonance.

  Plutinos
Despite their often extreme proximity to Neptune's orbit, the plutinos do not in fact have the possibility of encountering Neptune itself, because the periods of revolution about the sun of the plutinos and Neptune are precisely in a ratio of three to two.
This means that, after three revolutions of Neptune and two of a plutino (about 500 years), the relative positions of the objects in their orbits repeat, and this cycle does not give the bodies an opportunity to pass within 10 or more astronomical units of each other.
And whereas the plutinos orbit the sun at an average distance of 39 astronomical units, cubewanos have average distances over the range 42-46 astronomical units.

  Plutino   (Site not responding. Last check: )
In astronomy, a plutino is a Pluto-like object, insofar as it has the same relative orbit as Pluto.
These orbits are stabilized by an orbital resonance with Neptune, similar to Pluto's 3:2 orbital resonance.
Plutinos form the inner part of the Kuiper belt.

In astronomia, un plutino è un oggetto simile a Plutone, nel senso che ha un'orbita simile.
Queste orbite sono stabilizzate da una risonanza orbitale con Nettuno, simile alla risonanza 3:2 di Plutone stesso.

 Plutino
In astronomy, a plutino is a trans-Neptunian object that has a 2:3 orbital resonance with Neptune.
The distribution of all known plutinos (153 as of February, 2006) is plotted on the second diagram.
Numerical simulations suggest that Plutinos with the eccentricity 10%-30% smaller or bigger than that of Pluto are not stable in Gy timescales.

It is therefore natural to associate the presence of so many Plutinos with their interesting orbital properties.
A Cubewano is a main Kuiper belt objects, ones that are not influenced by the resonances of the outer planets.

 SPACE.com -- Planet 10? Tiny 'Plutino' Almost Qualifies
It's a plutino -- an object that orbits the Sun in the same amount of time as Pluto, but is too small to be called a planet.
Now's a great time to download the demo.The Plutino data file will work just as well with the demo as with the full version!
The object, 2000 EB173, was found in March using data collected by a 39-inch (1-meter) telescope at the CIDA Observatory in Venezuela.

 Up in the Sky: It's Plutino!
The minor planet or planetoid, officially named 2000 EB173, measures about 400 miles (650 kilometers) in diameter or about one-fourth the size of Pluto, a Yale astronomer said.
Because of its small size, the new planet is known as a "planetoid" or "plutino," which means "Little Pluto."
Astronomers spotted the minor planet using an unusually powerful telescope at the CIDA Observatory in Merida, Venezuela.

Plutinos: 2:3 resonance with Neptune, just like Pluto.
The perihelion of such an object tends to be close to Neptune's orbit (much as happens with Pluto), but when the object comes to perihelion, Neptune alternates between being 90 degrees ahead of and 90 degrees behind of the object, so there's no chance of a collision.

 Plutino
Plutino is de benaming voor hemellichamen (planetoïden) die qua grootte en baan met Pluto te vergelijken zijn.
Hun gemiddelde afstand tot de zon ligt tussen 39 en 40 AE (Pluto: 39,48 AE), de baanexcentriciteit is vrij groot (meestal tussen de 0,1 en 0,3; Pluto: 0,249), en ook is de baan vaak vrij sterk geheld ten opzichte van het gemiddelde baanvlak van de andere planeten (baanhellingen tot 40°; Pluto: 17°).
De volgende hemellichamen zijn geen plutino's maar cubewano's of scattered disk objects; qua samenstelling lijken ze op plutino's, maar zij bewegen in wijdere banen om de zon:

Furthermore, Pluto and estimated 30% of the observed KBOs move in 3:2 resonance with Neptune.
The capture of a Plutino into resonance and continuing synchronization at later times required the migration rate be below a threshold.
We found that in the Plutino problem the threshold migration time scale for resonant capture into 3:2 resonance was by one order of magnitude smaller than for capture into 2:1 resonance.

It was detected through a computer-aided search of thousands of images recorded in a single six-hour period on the night of March 15.
Other Yale researchers involved in the discovery were David Rabinowitz, associate research scientists in the Department of Physics, Bradley Schaefer, assistant professor of physics and astronomy, now at the University of Texas at Austin, and Ignacio Ferrin of the University of the Andes.
