∙ 13y agoThe planets Uranus and Neptune were discovered only in modern times after the heliocentric model had been generally accepted.

Why were Uranus and Neptune not included in the geocentric and heliocentric models?
The 8 "major planets" are (in size order) Jupiter, Saturn, Uranus, Neptune, Earth, Venus, Mars, and Mercury. By mass the order is the same except for Uranus and Neptune switching positions.The remainder of the known planets are the 5 dwarf planets, and about 2 dozen candidate dwarf planets, and the asteroids (aka minor planets) in the Main Belt between Mars and Jupiter.
A little bit - that's actually how Neptune was detected by Alexis Bouvard.
One, namely Neptune. Please note the following caveats:* That refers only to our own Solar System. * It refers to KNOWN planets; it now seems likely that there are at least 1-2 more planets, but they haven't been confirmed yet. * It uses the current definition of "planet". A few years ago, Pluto would have been included as well.
Mercury (22%), Jupiter (90%), Saturn (96%), Uranus (83%), and Neptune (80%) have mostly hydrogen gas in their atmospheres.
Actually, it's now eight, after scientists have decided that Pluto is not a planet, but a "dwarf planet". So the remaining eight in order from the Sun are as follows: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune. Or in an acronym way to remember, My Very Educated Mother Just Served Us Noodles.
Uranus is in the heliocentric system like all the other planets. The geocentric system is now only of interest historically. It wasn't correct.
Neptune and Uranus both have high concentrations of methane in their atmospheres.
yes...we get uranus and neptune. :) Americans get the moon? we get URANUS AND NEPTUNE.
Neptune and Uranus
Uranus is a greenish blue, and Neptune is blue.
Uranus is bigger than Neptune
Uranus is a little bit bigger if you measure it with Neptune, but even though Uranus is bigger- Neptune is actually heavier if you measure their weight. Which means even if Uranus is bigger, Neptune is heavier.
Neptune −201 °C. Uranus −197.2 °C.
They both are blue in colour.
I believe it can because Uranus is slightly smaller than Neptune.

Neptune's orbit and Uranus' orbit are never meeting, but Pluto and Neptune do have their orbits cross. :)
