|{{w|Comets}} and {{w|asteroids}}||{{sort|0280000|10<sup>5</sup> km}}||{{sort|0350000|100 AU}}||{{sort|013|0.15 mm}}||{{sort|02300|225 km}}||This is only the approximate region around where the words '''comets and asteroids''' is written in this large region. It goes from halfway to the previous label for ''Space junk'' and halfway to the next label for ''Oort cloud''. The max diameter is taken at this last point. A small part of this section just reaches into the Dwarf planet territory, making sense as {{w|Ceres}} is a dwarf planet in the {{w|asteroid belt}} which lies in this distance range. However, Ceres is much closer to Earth than the dwarf planet region. But that region is also the one where undiscovered dwarf planets should be! The main concentration of asteroids in the belt is between Mars and Jupiter. A very slim region in this log-log chart! Ceres is the only dwarf planet in the belt. The largest asteroid is {{w|4 Vesta|Vesta}} which is not gravitational rounded even with a diameter of 500&nbsp;km. It would not fit inside this part of the chart due to its size (and distance of 2.4 AU). The best known comet is {{w|Halley's Comet}} which returns every 75 year (next time in 2061). At that time it is much closer to the Sun than Earth at just 0.6 AU, but in 7 years time when it is the farthest away it will be out at 35 AU, further out than Neptune. But is it only of the order of 10&nbsp;km in diameter (11&nbsp;km in mean, 8&nbsp;km x 15&nbsp;km). So it can only be seen when close to the sun for a few months. This comet would fit inside this region for most of the time, when it is more than 2 AU from the sun, above the word "and" near the top of this part of the region over that word.

|{{w|Oort cloud}}||{{sort|045000000|1000 AU}}||{{sort|04000000|1 ly}}||{{sort|015|0.15 mm}}||{{sort|02500|500 km}}||For distance this is only the region where the words ''Oort cloud'' are written in this large region. This fits with the Wikipedia article that puts it in [https://en.wikipedia.org/wiki/Oort_cloud#/media/File:PIA17046_-_Voyager_1_Goes_Interstellar.jpg this range] from 1000 AU to more than one light-year (ly). The Oort cloud is speculated to stretch as far as 2 ly out from the Sun. It may even be so that the far edges of the cloud overlaps with similar clouds from the nearby stars, which are 4-6 ly away.
