The facts about every planet that we read in different sources are always approximate predictions until a probe really tests it. For example, Mars was thought to have 99 % CO2 in it's atmosphere but when the space probes tested it it came out that there was O2 present there too.
Probes or missions to planets vary in travel times depending on the distance between Earth and the target planet. For example, it can take anywhere from a few months to several years to reach a planet like Mars. The dates of these missions are carefully planned based on the alignment of the planets and optimal launch windows for efficiency and fuel savings.
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.
Scientists send unmanned space probes to outer space to gather data and images from distant planets, asteroids, and other celestial bodies. These missions help us learn more about the universe, the origins of our solar system, and the potential for life beyond Earth. Unmanned probes are also seen as a cost-effective way to explore space without endangering human lives.
Telescopes, Space missions, probes all help scientists discover more about the moon.

Yes, there are 44 missions.

Yes, the Voyager missions were run by NASA and they sent the probes.
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.
We have sent space probes to explore various planets in our solar system, including Mars, Venus, Jupiter, Saturn, Mercury, and Pluto. These missions have provided valuable information about the geology, atmosphere, and potential for life on these worlds.
they studied the structure of planets
The probes that can drive on planets are called rovers. NASA's Mars rovers, for example, are designed to explore the surface of Mars by traveling across the terrain and conducting various scientific experiments.
