The debate about the definition of the planets

Why does a group of researchers want to reopen the debate on the definition of planets?

The World Astronomical Union throws Pluto a bone - it and the trans-Neptunian bodies will be called plutoids

The number of planets in the solar system - does it really matter how much?

Were the changes in the definitions of the planets essential and how much their contribution affects the space sciences

New solar system(?)

In a flash - Pluto is still a planet

Astronomers challenge the decision to downgrade Pluto and call it a hijacker

"Many tearful eyes" at the IAU conference in Prague where it was decided to demote Pluto

The strict ones won - Pluto loses its status as a planet and becomes a 'dwarf planet'

Today the vote on the definition of the planets in the solar system * Proposal: adding the atmosphere as a criterion

"The very definition takes the magic out of the planets"

Eight stars?

12 Kochbia: the sequence of decisions regarding the determination of the definition of the planets

Changing the maps: the solar system will expand to 12 stars

There is a compromise in which the number of planets will increase to 12 and a waiting list of additional bodies will be opened

3,000 astronomers are currently meeting in Prague to discuss the fate of Pluto

Pluto's status as a planet will soon be decided

Finally - the tenth planet is bigger than Pluto

Nine planets? No longer!

Terrestrial planets, gas giants and ex-Neptunian planets instead of just planets

Planets in Planter

Workshop discovery: Are there other Earth-sized planets in the solar system?

The largest body since the discovery of Pluto in 1930 was discovered * Kva-Var orbits the Sun in a circle

Pluto is not suitable

How come a star is demoted
