Leet o Solar Seestem objects bi size

This is a **pairtial leet o Solar Seestem objects bi size**, arranged in descendin order o mean volumetric radius, an subdividit intae several size classes.

## Leet o objects bi radius

### Lairger nor 400 km

### Frae 200 tae 400 km

Aw imaged icy muins except Proteus wi radii greater nor 200&nbsp;km are roond, awtho those unner 400&nbsp;km that hae haed thair shapes carefully meisurt are nae in hydrostatic equilibrium. Maist asteroids are rockier an less likely tae be roond; for ensaumple, 10 Hygiea is nae, while 2 Pallas an 4 Vesta are borderline.

### From 100 to 200 km

This leet conteens a selection of objects estimatit tae be atween 100 an 200&nbsp;km in radius (200 an 400&nbsp;km in diameter). The lairgest of thir mey lie abuin the boundary for hydrostatic equilibrium, but maist are irregular. Most o the trans-Neptunian objects listed wi a radius smawer than 200&nbsp;km hae "*assumed sizes* based on a *generic* albedo of 0.09" syne thay are too far away tae directly meisur thair sizes wi existin instruments. Mass switches frae 1021 kg tae 1018 kg (Zg). Main-belt asteroids hae orbital elements constrained bi (2.0 AU  1.666 AU) accordin tae JPL Solar System Dynamics (JPLSSD). This leet is nae complete, missing mony poorly kent TNOs.

### From 50 to 100 km

This leet conteens a selection of objects 50 an 100&nbsp;km in radius (100&nbsp;km tae 200&nbsp;km in average diameter). The listed objects currently include maist objects in the asteroid belt an moons o the giant planets in this size range, but mony newly discovered objects in the outer Solar System are missing, sic as those included in the follaein reference. Asteroid spectral types are maistly Tholen, but some might be SMASS.

### Frae 20 tae 50 km

This leet conteens a few ensaumples acause thare are aboot 589 asteroids in the asteroid belt wi a meisurt radius atween 20 an 50&nbsp;km. Mony thoosands o objects o this size range hae yet tae be discovered in the Trans-Neptunian region. The nummer o deegits is nae an endorsement o signeeficant feegurs. The table switches frae &nbsp;kg tae &nbsp;kg (Eg), an mony o thir mass vailyies are assumed. *(See [[leet o minor planets]].)*

### From 1 to 20 km

This leet conteens anly a few ensaumples o objects atween 1 an 20&nbsp;km in radius.

### Below 1 km
