Venus
Venus is the home to thousands of volcanoes that have endured billions of years of widespread activity. It is the planet with the most volcanoes in the solar system. Fluid and water-like lava most likely created the volcanoes seen on mars by the Magellan. Magellan is a space probe that visited Venus in 1990. Venus' volcanic landforms are similar to Earth's. Shield volcanoes with broad bases and long lava flows, the largest spanning 6800 km long. Theia Mons is the biggest volcano on Venus, reaching 800 km wide and 4 km tall. The 150 large volcanoes on Venus are much smaller compared to Theia Mons, only stretching 100-600 km wide and 0.5 km tall.
Mars
Like Venus, Mars also has volcanoes. Mars, though, does not have as many volcanoes as Venus and they may only be found in certain regions of the planet's surface. Although Mars does not have many volcanoes, it does have the largest one in the solar system, Olympus Mons. Olympus Mons is as large as Ohio, eight times taller than Theia Mons on Venus, about 1 billions years old, and a shield volcano. Shield volcanoes (like Venus and Earth), lava flows, and cone-shaped volcanoes are all volcanic features present on Mars. On Mars, the volcanoes are about as old as our moon's volcanoes, dating 3.5 billion years old with Olympus Mon's lava flows over 100 million years old.
On both Venus and Mars, geologists have not found any evidence that volcanoes are still active. They believe that both planets once had burning, molten cores like Earth that powered the volcanic activity. Once their cores cooled down, the volcanoes stopped.
Moons
Our moon is dotted with light and dark colored spots that show where volcanic activity has and has not occurred. The light spots are craters that were formed as meteorites collided with the moon's surface for the past billion years. The other dark, abnormally smooth areas mark where over 3 billion years ago, lava once flowed.
Other than Earth's moon, Triton and Io are two moons in our solar system that have showed signs of volcanic activity, seen by the space probe, Voyager 1. The volcanoes on these two moons are very different from that on any of the other planets. One of Neptune's moons, Triton, is so cold it has areas of frozen nitrogen. The surface of this moon is made up of ice and other frozen materials that soak up the sun's heat. From there, the frozen nitrogen melts slightly, expands, then erupts.
Io is a moon of Jupiter that geologists have found to have volcanic activity. Sulfur volcanoes erupt on this moon. They explode over the surface like fountains or umbrellas.
