They could, but as of now, no astronauts have travelled to any other planets in the solar system.
Astronauts have not landed on Uranus and Neptune, as they have only visited the Moon, Mars, and the satellites of Jupiter and Saturn. Exploration of these distant gas giants would require advanced technology and significant challenges to overcome.
So far, with current technology, yes. Note that the nearest stars are in the order of 10,000 to 100,000 times farther than the planets in our own Solar System. You might imagine a technology that allows astronauts to travel to such other star systems, but that would require enormous technological breakthroughs, and the trip may well take generations - or require the astronauts to be put in some sort of artificial hybernation - another technological breakthrough we haven't achieved yet.
That's simple. They could look through a telescope and see some planets near the earth, but not all. Astronauts travel in space and study them.
No astronaut has travelled to a different planet. If they were to do so it would be for exploration and exploitation. Astronauts are known to explore and travel for the benefit of the others.
Sheer distance. We are talking about millions and millions of miles alone between Earth and Mars. When you factor in the distance between other planets, like from Jupiter to Saturn, the expanse of space only grows. It takes time to travel that far.

In any solar system; that's what planets do.

A heliocentric system.

No stars travel around Mars. Stars are distant celestial bodies that appear fixed in the sky due to their immense distance from our solar system. Mars, like Earth, revolves around the sun in its orbit.
The planets travel around the sun in elliptical orbits due to the sun's gravitational pull. This movement is known as the heliocentric model, with the sun at the center of the solar system, contrary to the geocentric model where the Earth was believed to be at the center.
The sun and its family of planets, dwarf planets, moons, asteroids, and comets make up the solar system. The sun is a star that holds about 99.8% of the solar system's mass and provides energy that sustains life on Earth. The planets orbit the sun in elliptical paths with the inner planets being rocky and the outer planets being gaseous. Each body in the solar system plays a unique role in the dynamics and balance of this celestial system.
Planets travel in elliptical orbits.
It is obviously the solar system.
