Question

Какую группу небесных тел астрономы к 2006 году называли малыми планетами?

Answer 1

 К малым планетам относятся карликовые планеты и астероиды, а не входят в их число кометы и тела с диаметром менее 30 м — метеороиды.

Answer 2

Small Planets Group as of 2006

As of 2006, astronomers referred to a group of celestial bodies as "small planets." These small planets are also known as dwarf planets and include objects such as Pluto, Eris, Haumea, Makemake, and Ceres.

This classification was significant in the context of the debate surrounding the reclassification of Pluto from a planet to a dwarf planet. The International Astronomical Union (IAU) officially defined the term "dwarf planet" in 2006, leading to the reclassification of Pluto and the recognition of other similar celestial bodies as part of this group.

The term "small planets" was used to encompass these celestial bodies that share characteristics with planets but do not meet all the criteria to be classified as full-fledged planets according to the IAU's definition.

This classification has implications for our understanding of the solar system and the diversity of celestial bodies within it.
