How do scientists know there are other planets in the solar system if they never made it there?

The invention of the telescope enabled scientists to observe the motion of planets, which the ancients called 'wandering stars'. Mathematical formulas have enabled astronomers to model and understand planetary motion. Occultations (eclipses) and spectrographic analysis increase the data that can be obtained from observation. Of course, all of this information is subject to revision (Pluto's size was once thought to be equal to Earth's) as unmanned space probes continue to provide some of the best images and details of the planets they have been sent to study.

Why do scientists believe that you may have to live on other planets in the future?
Eventually the sun will blow up and the solar system will be destroyed.
Is there life like aliens on other planets?
We don't know if there is life on other planets or not. Most scientists suspect that there probably is life somewhere in the Universe other than Earth, but we've never found any yet.
what is the difference between the scientists and ours solar system?
the difference between our solar system and the scientists is that we put terrestrial and gas giants where as they only put planets. Do u guys know any other ones?

NO! well not what scientists has discovered yet
Is life on other planets against Christian faith?
scientists can't really find if there is life on other planets
Why did scientists begin to question the early models of the solar system?
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.
