Axes list distances in AU, projected onto the ecliptic, with ecliptic longitude zero being to the right, along the "x" axis).
Positions are accurate for January 1st, 2000 (J2000 epoch) with some caveats:
For planets, positions should be exact.
For minor bodies, positions are extrapolated from other epochs assuming purely Keplerian motion. As all data is from an epoch between 1993 and 2007, this should be a reasonable approximation.
In the Kuiper Belt, radial "Spokes" of higher density, or gaps in particular directions are due to observational bias (i.e. where objects were searched for), rather than any real physical structure.
العربية: صورة توضح توزيع الأجرام في المنطقة الوراء نبتونية. حيث يبدو حزام الكويكبات بلون زهري، وأجرام القرص المبعثر بلون برتقالي وأجرام حزام كايبر بلون أخضر، أما سحابة أورط فهي بعيدة وكبيرة جدًا لكي توضع ضمن رسم بهذه المقاييس.
