Sending space probes is cheaper than sending people to other planets because space probes are typically smaller, lighter, and require less infrastructure to support life support systems and return missions. Human missions have to account for the safety, health, and well-being of the astronauts, resulting in significantly higher costs. Additionally, space probes can be designed for specific tasks and don't require return trips, whereas human missions would need to account for the return journey.
Most famously, it was voyager 1 and 2 that explored these outer gas planets and have given us so much information. Other probes have been sent to these gas giants, but these are the the probes that visited all four gas giants between them.
No they aren't the same. A satellite is on a defined orbit and a probe is something sent to discover planets or other space objects.
Space probes are designed to explore and study heavenly bodies such as planets, moons, asteroids, and comets in space. They collect data on the composition, atmosphere, surface features, and other characteristics of these celestial objects to help scientists better understand the universe and its origins.
Space probes carry instruments like cameras, spectrometers, magnetometers, and seismometers to collect data on planetary surfaces, atmospheres, and magnetic fields. These instruments help scientists study the composition, geology, and other properties of planets and other cosmic objects.
The Pioneer 10 and Pioneer 11 probes flew past Jupiter before continuing their journey outward to deep space. The Voyager 1 and Voyager 2 probes also conducted flybys of Jupiter, Saturn, Uranus, and Neptune before heading towards interstellar space.

There have been a number of robotic exploratory vehicles sent from Earth to other planets and asteroids, but there is no indication that other planets have sent any probes to Earth. Of course, we would not necessarily see it. It might be designed to be inconspicuous, a stealth probe.
To send a person to another planet, you would also have to send everything else that keeps that person alive. For every kg that you send into space you have to pay a huge sum of money, it costs loads of money in fuel. So to send a person you have to then consider the cost of sending the food they need, water, oxygen and everything else for the duration of the trip. For a probe, you just need to sent the equipment and a power source.
Yes. Probes have already be sent to the Moon, and other planets; this requires a velocity very near the escape velocity from Earth. Other probes are leaving the Solar System, so they achieved the much higher escape velocity required to escape the attraction from the Sun.
Space probes leave Earth, they do not go toit.
Robotic space probes have provided us with the most information about other planets. These probes can fly by, orbit, or land on other planets to gather data and images, allowing scientists to study the composition, atmosphere, and geology of these worlds in detail. Examples include missions from agencies like NASA and ESA.
Earth has launched over 100 space probes since the 1950s. These probes have been sent to study planets, moons, asteroids, and other bodies in our solar system, as well as to explore deep space beyond.
they help us find out about other planets by taking photos and collecting rock samples.
Space probes help scientists study other planets by collecting data such as images, measurements, and samples that provide valuable information about the planet's atmosphere, surface, and composition. They can also help scientists understand planetary processes, such as geological activity and weather patterns, by observing the planet over an extended period of time. Additionally, space probes can provide insights into the potential for past or present life on other planets.
Voyager 1 and 2 visited the outer planets and went on into interstellar space.
