Galileo was sent to a Jesuit monastery for his safety after being found guilty of heresy for supporting the heliocentric model of the solar system, which contradicted the teachings of the Catholic Church at the time. He was placed under house arrest there for the remainder of his life.
Galileo Galilei proposed a heliocentric model of the solar system, where the sun is at the center and the planets orbit around it. This contradicted the prevailing geocentric model, in which Earth was believed to be at the center of the universe. Galileo's observations with the telescope provided evidence to support the heliocentric theory.
To find whats in it. We are exploring the solar system to gain knowledge about it's contents. Many scientists are intrigued by the solar system and it's many planets and stars, therefore want to learn more about them.
How exactly do you "discover the Solar System", considering that it is in plain sight? - The Sun, Moon, and planets were already visible to prehistorical people. The Ancient Greeks noticed that the planets moved around the Sun. You may also want to investigate about "heliocentric system" - i.e., the idea that the Sun is at the center, and that the planets move around it.

There is only one star in the solar system - it is the Sun.
There are "aliens" in the solar system... as long as you're not referring to little green men that want to suck out our brains, they would be microscopic organisms living in icy objects in the solar system, I'm pretty sure.
The smallest member of the Solar System is a dust grain such as a micro-meteoroid. Or if you want to get a lot smaller, then a hydrogen atom. Even smaller, a neutrino from the Sun.
His Father, for he didn't want Galileo to major in mathmatics, but to major in medicine instead.
most people want to discover life
There are a lot of ways to explore the solar system. Some people, like NASA, see the solar system in stars by the Hubble Telescope satellite. But that satellite only checks the Earth. In order to explore the whole solar system, you must travel to Mars, Jupiter, Saturn, Uranus, and Neptune (Pluto is not considered as a planet in the solar system in this answer). If you want, you can also explore Venus and Mercury. But you cannot land on Mercury, especially on Venus (the hottest planet in the solar system). So now astronomers/astronauts only explore Mars - Neptune.
