Final answer:
The height comparisons between volcanoes on various planets highlight the extraordinary scale of extraterrestrial mountains like Olympus Mons on Mars, which dwarfs Earth's tallest peak, Mount Everest.
Step-by-step explanation:
The question concerns the maximum heights of volcanoes found on different planets, with a particular focus on a recently discovered planet's volcano.
When comparing such heights, we need to take into account the measurements provided for volcanic heights on Earth, Venus, and Mars.
For instance, Mount Everest is the tallest mountain on Earth, with a height of 29,028 feet, whereas Olympus Mons on Mars is over 20 kilometers high, significantly taller than any mountains on Earth.
Using the conversion factor where 1 kilometer equals 3,281 feet, we can determine the height of these volcanoes in different units of measurement.
