There may be a planet out beyond Pluto that is 30-70% Earth's mass,but it still won't be a planet?

Default There may be a planet out beyond Pluto that is 30-70% Earth's mass,but it still won't be a planet?

For comparison:
Mercury: 5% Earth's mass
Mars: 10% Earth's mass
Venus: 88% Earth's mass

Yet an object bigger than either Mercury or Mars, in orbit around the
Sun, would not be a planet? Interesting.

If something that big exists (very speculative) and it has betrayed its
presence by dynamical effects on other large bodies, then it would be a
planet by the "cleared it orbital path" part of the definition, however
badly that bit is worded.

Wait and see. There have been previous claims that outer solar system
dynamics are due to a large planet, and none of these claims came to
anything.

Pluto is a planet. One sees a table, and because it is smaller it is
still a table. It is the shape. Pluto is round and has three Moons and
as a planet it goes around the Sun.

Now if Saturn and Jupiter would cross paths, which one would not be a
planet? The answer is 'ridiculous', and Pluto is a planet.

If it has things called moons, it must be a planet. The Sun's moons
are planets, the planets' moons are moons. Pluto has moons, orbits
around the Sun as a planet.
A planet has no rules, because a planet orbits around the Sun, it is
the Sun's moon, a round object with considerable planetary shape,
round, natural. The Sun defines a planet as it rotates around the
Sun.

If planets cross and have no perfect round paths, then planets cross
paths. One cannot point to an object that is five times the size of
Jupiter and it orbits the Sun that it is not a Sun's planet.

Most people would have a peace of mind having Pluto back as a planet
in our solar system.

Crazy politics, crazy science, crazy determinations, categorizations,
ideas, Western brain of marxes of power in the heads, false ideas,
subjectively lame aptitudes, impersonal control, religion, and
elements of easy discriminations where things are falsly categorized
and manipulated as a sick mundane.
