Are mars and Jupiter alike

Answer 1

Mars is the most explored planet other than Earth. It's named after the ancient Greek God of War, and is the 4th planet from the sun. It's about 1.5 AU from the sun. It has a thin atmosphere with polar caps made from water and carbon dioxide. The surface temperature averages from 186 K (-125 F) to around 268 K (-51 F). Surface pressure is only about 8% of the Earths, which is roughly how much pressure you would be under if you were 20 kilometers above ground on Earth. Because of the low pressure and thin atmosphere, people could not survive on Mars surface without protection. The fact that there is an atmosphere present, though, and the temperature ranges aren't completely hostile, we might not need a space suit, just an environment suit, something to keep us warm and give us more oxygen and pressure. Mars has 2 moons - Phobos and Deimos, named after ancient Greek personifications of fear, Horror, and dread that followed Mars into war. Currently, it has satellites orbiting and the most popular probes have been Mars Exploration Rovers, which searched for liquid water or looking for life.

Jupiter is the largest planet in the solar system. It is named after the patron male god in the Roman pantheon, and is the 5th planet from the sun. It's about 5.2 AU away from the sun, and belongs to a class of planets called gas giants. It's mainly composed of hydrogen, but also a large amount of helium and other trace elements and compounds in the atmosphere. No one is sure what the interior looks like because it is believed there is no real "surface", just a rocky core surrounded by liquid and gas. Jupiter has many moons - at least 63, and the 4 largest are called Galilean moons (named after Galileo, the man who discovered them). Since Jupiter has such a strong gravitational field, as these moons orbit they're subjected to tidal forces that cause them to flex and heat up, which makes them geologically active.

Here is a list of Galilean moons and characteristics:

1. Io - very thin atmosphere and active volcanoes. Hot lava flow on surface, which scientists think is made of hot sodium-rich rock.
2. Europa - covered by a thick sheet of water ice with possibly a salt water ocean beneath. It is one of those places scientists think life might be, because of its liquid ocean and thin oxygen atmosphere.
3. Ganymede - the largest moon in the solar system. It's even bigger than Mercury, and believed to have a water crust similar to Europa and a very thin oxygen atmosphere.
4. Callisto - heavily cratered, thick ice surface and possibly salt water ocean below. Thin atmosphere made of carbon dioxide.

Answer 2

Mars and Jupiter are not alike. Mars is a terrestrial planet, smaller and colder than Jupiter. Jupiter, on the other hand, is a gas giant, much larger and composed mostly of hydrogen and helium. They have different compositions, sizes, and characteristics.
