Telescopes, Pictures,Satellites, and Probes
While many space probes near the Sun (or not too far away, like satellites near the Earth) are solar powered, the designers of the Voyager probes knew that the spacecraft would be going out from the solar system to distances where the Sun is merely a bright star. So the Voyager probes use a nuclear thermal power source.
There is much space debris. Humans have many decayed satellites and probes floating around.
depends on how much knowledge you have on solar system! Study hard!!! it also depend on what division your in.
Telescopes, Space missions, probes all help scientists discover more about the moon.
Without space probes, the only knowledge we have of the solar system comes from ground-based telescopes. That's how we did it for 300 years before satellites.
By robotic probes.
Simpler and cheaper.

Voyager 1 and Voyager 2. There is a matter of some debate as to whether the two Voyager probes have actually left the solar system, an where the "edge" of the solar system actually is. Both are beyond the orbit of Pluto, but have not passed beyond the vaguely-defined Kuiper Belt, and the two probes are just approaching the heliopause, the boundary layer between the solar wind and the broader currents of interstellar space. But it seems likely that however that boundary is defined, the two Voyager probes either were or will be the first man-made objects to pass it.
Telescopes, Pictures,Satellites, and Probes
In the solar system, we have a star, planets, dwarf planets, asteroids, comets, meteors, and human debris. (such as old satellites, probes, etc.)
The Voyager 2 went to Neptune on it's last stop in the solar system.
Satellite/s, space probes, telescopes and many other ways.
There have been a series of robotic probes to every planet in the solar system, and the two Voyager probes are approaching (or perhaps have just passed, we're not yet sure) the "edge" of our solar system. But no human has ever been further away than the Moon.

The Sun, moons , planets, asteroids, comets, meteoroids, dust, gases are all in our solar system. There are also man made objects floating around such as satellites and space probes.
