do the solar system compose of 12 planets?

Question

please dont send stupid answers to this question. thank you for all the people who share their answers.

Answer 1

8 planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn (known since antiquity) + Uranus (discovered 1781) + Neptune (discovered 1846)

3 dwarf planets: Ceres, Pluto and Eris. NB Eris is slightly bigger than Pluto but Ceres is quite a lot smaller.

If you want to disregard and blur the distinction between planet and dwarf planet and call that 11 and make that 12 because you choose to regard Pluto and Charon as a double planet (no definition exists as yet) no-one can stop you but that view has no official basis or backing,

Sedna, contrary to popular opinion, has no official status as yet. It is about two-thirds the size of Pluto.

Pluto used to be defined as a planet but so did 1 Ceres, 2 Pallas, 3 Juno, 4 Vesta, 5 Astraea, 6 Hebe, 7 Iris, 8 Flora, 9 Metis, 10 Hygiea, 11 Parthenope, 12 Victoria, 13 Egeria, 14 Irene and 15 Eunomia (the first 15 asteroids to be discovered) and until they were demoted from that status in the 1860s we had 23 planets (the 8 named in the first paragraph above plus these 15),

As regards extra-solar planets, we know of 212 of these, all in the Milky Way, varying from Epsilon Eriuani b10.5 light years away to GLE-2005-BLG-390L b. This is the most distant and probably the coldest exoplanet found to date. It is believed that it orbits a red dwarf star around 21,500 light years from Earth, towards the center of the Milky Way galaxy.

Answer 2

8 planets as we know from Mercury to Neptune. Previously it was 9 (comprising pluto). Ceres, is unspeakable as it may be a planet because it's larger than Pluto. So it's 9 again (It may be). Eris and Sedna (distance from sun - 8400 million km) are two other newly discovered planets. With this we have 11 planets, we can't have 12.

I know a planet was discovered recently. It was found 30000 light years away from earth near the constellation Sagittarius. That can't be a planet because our solar system isn't so big. It was seen like a dot from the telescope revolving around a star.

Answer 3

According to the new definition of planets, our solar system has 8 planets; They are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; and 3 dwarf planets, Ceres (previously considered an asteroid), Pluto (previously considered a planet), and Eris (a recently discovered object larger and more distant than Pluto).

Answer 4

not 12 but 10, cause they thaught we had 9, then they found another one, then another one, but then they found out that pluto is not a planet,

Mercury, Venus, Earth, Mars,Jupiter, Saturn, Neptune, Uranus,(pluto),Planet X, Then I forgot the last one srry.

Answer 5

Nope, 8.
