Mariner 9 took on that spacecraft's mission of mapping 70 percent of the Martian surface in addition to its own objective of studying changes over time in the Martian atmosphere and surface.
A moon? I don't think a planet orbiting another planet would be called a planet.
Mariner 9 was a NASA space probe that became the first spacecraft to orbit another planet when it entered orbit around Mars in 1971. It mapped 85% of the Martian surface, providing valuable data and images that revolutionized our understanding of the planet.
Mercury has the most eccentric orbit in our solar system, and it occasionally crosses the orbit of Venus. Its elliptical path also brings it close to the Sun, resulting in extreme temperature variations on the planet's surface.
The moon closer to the planet would complete an orbit first because it has a smaller orbit, which means it has a shorter distance to travel around the planet compared to the moon that is farther away.
Mariner 9 became the first spacecraft to orbit another planet, Mars, on November 14, 1971. It was launched by NASA on May 30, 1971, and successfully entered Mars' orbit after a journey of about 167 days. The mission provided groundbreaking data and images of the Martian surface, revealing features like volcanoes, canyons, and evidence of past water flow.

No human has ever set foot on another planet
Adding a second planet affects the orbit of the first planet through gravitational interactions. The gravitational pull between the two planets can cause changes in the orbit of the first planet, such as variations in its speed, shape, or orientation. These gravitational influences create a complex system where the orbits of both planets are interconnected and can influence one another over time.
its orbit crosses with another plant
We call that path the "orbit" of the orbiting body. Note: You would not ever see a planet orbiting another planet. At least, if you did, you would not call them both planets.
A moon is an object that orbits a planet. A planet cannot orbit another planet.

You are thinking of Pluto. Pluto is now designated a minor planet.
A planet with an eccentric orbit that crosses the orbit of another planet would create gravitational interactions and potential collisions between the two planets. This scenario could lead to disturbances in their orbits, potentially causing erratic behavior and possible impacts between the planets.
An orbit is the path of a planet, star, or satellite through space around another object. The path the orbit is simply the orbit.
Pluto cuts across Neptune's orbit about once every hundred years. This is because Pluto has an ovalish orbit around the sun and Neptune has a round one.
