It's not; normally scientists use satellite telescopes and send them around the solar system to take pictures and record data of the planet.
scientists can use them to study the early solar system
Yes, it is. At 2006, the scientists decided that it was not a planet of solar system. Now, there are just eight planets in the solar system.

to observe the solar system
N.a.s.a
because of scientists
Scientists are currently using mirror telescopes in space that do not have to deal with light pollution and are more clear than lens telescopes to take pictures of the solar system. They are also using radio telescopes to try and discover extra terrestrial life.
Because it was originally believed that the Earth was the centre of the solar system. Observations by scientists over time later proved the sun to be at the centre of the solar system, and that all other planets revolve around it.
There are countless solar systems that we are not aware of. One of the best known solar systems by scientists is our solar system, which rotates around the sun and includes nine planets.
No one knows it. Scientists lie or exaggerate about knowing. Although the above is partially true, scientists do have theories about how the solar system was formed. If the entire solar system was formed at the same time then all objects in the solar system are the same age. Using radioactive dating of meteorites scientists calculate how long it has been since the meteorite solidified and go based on that date.
Scientists classify small objects in the solar system by size, shape, and composition
