Location of the Asteroid Belt between Mars and Jupiter

Click For Summary

Discussion Overview

The discussion revolves around the location and characteristics of the Asteroid Belt situated between Mars and Jupiter. Participants inquire about its dimensions, orbital properties, and the nature of the debris within the belt, exploring both theoretical and observational aspects.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant asks about the starting and ending radii of the Asteroid Belt from the Sun, as well as its Right Ascensions and Declinations.
  • Another participant states that the main asteroid belt is primarily located between the orbits of Mars and Jupiter and suggests it may be remnants of a planet that either was destroyed or failed to form.
  • A question is raised regarding the breadth and width of the asteroid belt in Right Ascension (RA) and Declination (DEC).
  • It is noted that the belt lies mostly within the ecliptic plane.
  • Participants discuss the dispersion of debris in the ecliptic, questioning whether it resembles the rings of Saturn or has a broader distribution.
  • One participant claims that the asteroid belt is dispersed uniformly about its orbit and provides an approximate width of 180 million km, though it is acknowledged that the belt does not have a "hard" width due to the independent orbits of its bodies.
  • Another participant defines the main asteroid belt as being between 2.0 AU and 3.5 AU, suggesting that objects outside this range fall into different categories.
  • A participant shares a resource that helped them determine the declination characteristics of asteroids, noting the inclinations of objects within the specified semi-major axis range.

Areas of Agreement / Disagreement

Participants express varying views on the specific dimensions and characteristics of the Asteroid Belt, with no consensus reached on the exact definitions or properties discussed.

Contextual Notes

There are limitations in the discussion regarding the assumptions made about the nature of the asteroid belt and the definitions of its boundaries, which may depend on varying interpretations and observational data.

There is an Asteroid Belt between Mars and Jupiter. I have a few questions about it. Where does it start and end (Radius from the Sun)?
Also, the Right Ascensions and Declinations of the extents of the belt or if it is continuous around the sun?

I know that some of the larger asteroids and Ceres have elliptical orbits so humor me.

Some websites would be helpful.

The 'main' asteroid belt is mostly between the orbits of Mars and jupiter. It is thought to be the remnants of a planet that was torn apart, or was unable to form in the early solars system. For further discussion see

Does the main asteroid belt have a breath and width in RA and DEC?
 
It lies mostly within the ecliptic.
 
But how big and the location of the debris in the ecliptic. Is it like the rings of Saturn or is it a larger dispersion.
 
It is, in fact, dispersed pretty uniformly about its orbit.

Of course, the asteroid belt, being a swarm of independently orbiting bodies, does not have "hard" width but according to http://www.bnsc.gov.uk/4749.aspx it is approximately 180 million km in width.

I think the Main Belt is defined as being between 2.0 AU and 3.5 AU. Outside of that and objects fall into different categories. Nature, of course, is under no obligation to fit our preconceptions.
 
I answered my own question about the asteroids in the Declinaton dircection using this site:

http://ssd.jpl.nasa.gov/dat/ELEMENTS.NUMBR

This site shows all the major dwarf planets and asteroids. I just looked at all the inclinations,i, for a semi-major axis,a, between 2 and 3.5AU and found the largest i to be about 64deg for about the first 1000 or so averaging between 10-30deg.
