Uranus was discovered by William Herschel on March 13, 1781, 229 years ago.
Neptune, however, was first observed on September 23, 1846, only 164 years ago.
Of course they had been in the solar system for a few billion years.
It's just that they weren't in our model of the solar system, until discovered.

∙ 10y agoYes, Uranus and Neptune have always been part of the solar system. They were discovered in the late 18th and mid-19th centuries, respectively. Uranus was discovered in 1781 and Neptune in 1846.
Neptune is the eighth planet from the sun. It is about the size of its neighboring planet, Uranus. It has a Great Dark Spot that swirls in its atmosphere.it is located between uranus and the kuiper belt.
Neptune's years are 164.8 Earth years. Its days are 16 hours and 6.7 minutes long. Although Neptune's days are shorter than our days, its years are still longer than ours.
Neptune, a planet in our solar system, does not have any specific myths or legends associated with it as it is a celestial body without a cultural context. In Roman mythology, Neptune is the god of the sea, but there are no specific myths focused solely on the planet itself.
It takes approximately 84 Earth years for Uranus to orbit the Sun, around 165 Earth years for Neptune, and about 248 Earth years for Pluto.
Uranus likely experienced a collision with a massive object in the early solar system, causing it to be knocked on its side and creating its extreme axial tilt of 98 degrees. This collision likely occurred billions of years ago and is a unique feature that sets Uranus apart from the other planets in our solar system.
It orbits round the Sun in an orbit between Saturn and Neptune, one trip round takes 84 years.
Neptune was formed around 4.5 billion years ago, along with the other planets in the solar system. Neptune is the fourth largest planet, after Jupiter, Saturn, and Uranus. Almost identical in size to Uranus, its sister planet, Neptune was formed, along with the other planets, from the primordial Solar Nebula. While the larger planets (Jupiter and Saturn) received the lion's share of the nebula's hydrogen and helium, Uranus and Neptune appear to have received only rock and ice
The planets formed in the solar system about 5 billion years ago, they weren't "added to it" later. The discovery of the planets is lost in the mists of prehistory, except for Uranus (1781) and Neptune (1846).
There are currently 8 planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune) in our solar system, with Pluto having been demoted to dwarf planet a few years ago.

All planets in the solar system spin on their axes. This spinning motion causes day and night cycles on each planet. The direction of rotation varies among the planets.

The planets that are farther from the Sun than Earth are (in this order): * Mars * Jupiter * Saturn * Uranus * Neptune and sometimes Y, er, I mean the Dwarf Planet Pluto. (It's 'sometimes' because Pluto's orbit brings it closer to the Sun than Neptune part of the time [most recently for 20 years ending in 1999] which is one of the reasons why it was reclassified as a Dwarf Planet.)
There is no new planets: the ones in the Solar system have been around for about 4 billion years! All but two: Uranus and Neptune are visible to the naked eye and so mankind has known about them for ever. The last planet to be discovered was Neptune, in 1846. So nothing new.
