What is the diameter of Mars?Planets in Our Solar SystemYou might know that our solar system has eight regular planets. Some are larger than Earth, while others are smaller. Mars, the fourth planet from the sun
Earth's moon is about 2,159 miles in diameter and is, on average, about 240,000 miles away from Earth. Unlike Earth, the Moon does not have much of an atmosphere, which is one of the reasons there is no life on the Moon.

They range in size from mighty Ganymede, the largest in the solar system at more than 5,200 kilometers across—wider than the planet Mercury—to the tiniest that we’re able to see from Earth, at roughly 1 km in diameter. Saturn is more distant from us than Jupiter, so its moons are...
Types of Telescopes A telescope's optical tube has two important parameters: "aperture" and "optical quality". Aperture is the diameter of the objective lens or a mirror - it defines how much light the telescope gathers and its maximum resolving power. Optical quality is a general therm whic...
Three very large volcanoes are found on the Tharsis bulge, an enormous geologic area near Mars’s equator. Northwest of Tharsis is the largest volcano of all: Olympus Mons, with a height of 25 kilometers and measuring some 700 kilometers in diameter at its base. The three large volcanoes ...
The largest terrestrial planet, Earth has a diameter only one quarter as great as the diameter of the smallest Jovian planet, Neptune, and its mass is only one seventeenth as great. Hence, the Jovian planets are often called giants. Also, because of their relative locations, the four Jovian...
Largest planet: Jupiter, roughly 88,846 miles (142,984 km) across, about 11 times the diameter of the Earth. Largest moon: Ganymede, which orbits Jupiter, is roughly 3,273 miles (5,268 km) in diameter and is a little larger than the planet Mercury. ...

That episode was recorded just before the James Web Space Telescope was launched and deployed. Just to recap, the Webb is the largest space telescope ever built. Its mirror has a diameter of 6.5 meters or 21.3 feet. As a point of comparison, the Hubble Space Telescope has a diameter of ...
