Why aren't the ten smaller satellites discovered until a space probe passed close to Uranus?

Uranus is very far away. The planet itself cannot even be seen without a telescope. Those ten moons are very small. They would have been extremely difficult to find with even the best telescopes.

Why werent the ten smaller satellites discovered until a space probe passed close to to uranus?
Since Uranus is a long distance from earth and the 10 smaller satellites are so small and dark, we weren't able to discover them until we sent a spacecraft close to Uranus. These satellites are not visible from earth.Uranus is very far away from the Sun and the Earth, and its satellites very small. When Voyager flew there it was much closer and it was easier to detect them.Space probes have proved that Uranus also has ten much smaller satellites that orbit much closer to the planet. These ten are dark in color and do not reflect as much sunlight as the larger ones.

Because they are dark in color and don't reflect as much sunlight as the larger ones.
How many satellites went to Uranus and what year?
As of now, no spacecraft or satellites have been sent to Uranus. However, there have been missions that have conducted flybys of Uranus, such as Voyager 2 which passed by the planet in 1986, providing valuable data and images. There is a proposed mission called Uranus Pathfinder that aims to send a dedicated orbiter to Uranus in the future, but no specific year has been set yet.
What spaceships passed Uranus?
So far only Voyager 2 has visited Uranus.
Does Saturn have any artificial satellites?
A natural satellite is a moon. Saturn has sixty-two known moons, fifty-three of which actually have official names. There are hundreds of smaller objects that make up Saturn's rings. Saturn's moon Titan is larger than the planet Mercury, and is the second largest moon in the solar system.

Why di astronomers thought there might be many objects beyond Neptune?
In the same way as astronomers thought there was an object beyond Uranus leading to the discovery of Neptune. Neptune caused perturbations ('wobbles') in the orbit of Uranus because of its gravitational pull as the two planets passed each other - as Uranus passed Neptune on its journey round the sun. This wobble meant that something further out was causing Uranus to do this, and so Neptune was discovered. Early in the 1900s it was discovered that Neptune also had perturbations - 'wobbles' in its orbit - and so another planet further out was believed to cause this. Clyde Tombaugh was given the task of trying to find it, when he discovered Pluto. However, when the size of Pluto was determined it was believed that this was too small an influence on the perturbations measured and so the existence of 'Planet X' - a large planet beyond Pluto - was still mooted. However, in recent times it was realised that the results of measurements of perturbations of Neptune's orbit should be put down to experimental error, and so Planet X does not exist as such - although many more smaller minor planets have been discovered since then.

Has any satellites and robots showed up on Jupiter and what years?
No satellites or robots have ever shown up on Jupiter as far as we know. We have sent our own exploration probes that have passed Jupiter.
What space probes or satellites have studied Neptune?
Voyager 2 passed by Neptune on August 23, 2009
What is the best thing about planet Uranus?
Uranus (despite the name) is a awesome world. It has been knocked by Earth sized planetesimals and orbits the Sun with a 98 degree angle of axial tilt. It is an "ice giant" planet with ices like ammonia in the upper atmosphere and in its interior. It is also the coldest planet in the solar system. All its moons are named after Shakespearean characters including Miranda and Puck. It was the first planet discovered by telescope and its rings were discovered when they passed in front of a star. It has a lovely green / blue colour and is in my opinion (after Earth) the most beautiful planet in the solar system. I think the best thing about planet Uranus is its discovery with only a "backyard" telescope. So don't dis Uranus!
When was Moreton Bay discovered?
It was first discovered 15 May 1770 James Cook when he passed the area
What are facts about the moons of Uranus?
Like all the outer planets, Uranus is surrounded by a swarm of moons. As of 2011, there are 27 known and named moons. Five are large icy satellites that were discovered from Earth, eleven were located by Voyager 2 in 1986, and the rest in telescopic surveys since 1997. The orbits of the inner 13 moons are intimately connected to the rings of Uranus, which are thin and tenuous. These moons are small, none larger than 162 km in diameter and some as small as only 18 to 30 km. The orbits are thought to have changed substantially since they were first established. The outer 9 moons are thought to be captured asteroids, and all but one orbit in the opposite direction from the five large moons, and millions of kilometers farther from the planet. The outermost, Ferdinand, averages 20 million km from Uranus and is estimated to require 7.7 Earth years to make a single orbit of the planet. Although Voyager 2 performed a survey of Uranus' moons, it passed by when tilted Uranus was at the height of southern summer. As a result, only the southern hemispheres of Uranus's moons have ever been imaged by spacecraft. Additionally, the "bull's-eye" pattern of Uranus' rings and moons on the sky meant that Voyager 2 saw only Miranda close-up; the rest of the moons were only seen distantly.
How many man-made satellites does Jupiter have?
As of June 2011, Jupiter has 67 confirmed natural satellites, or "moons" orbiting the planet Jupiter. 50 are named moons and 17 have provisional designations based on the year they were first sighted. (see the related question and links)
