Australia has a surface area of 7.6 million sq. kilometers and a volume of 304 million cubic kilometers while Titan is the second largest moon and a spherical entity with a surface area of 83 million sq. kilometers and a volume of 71.6 billion cubic kilometers. It only makes sense that Titan would be bigger as it is a spherical whilst Australia is a flat land mass.
Continue reading for a more detailed breakdown of what makes both Australia and Titan as big as they are along with some of the larger elements that can be found on each of their surfaces.
How Big Is Australia?
Australia is the sixth largest country in the world, following Russia, Canada, China, the USA, and Brazil. This commonwealth country comprises mainland Australia plus Tasmania and several other smaller islands; this land has a total area of 7,617,930 sq. km.
As for the overall volume of Australia, if we consider that Earth’s crust ranges from around 5 to 70 km in thickness. Generally, this crust is thicker under the continental land, which averages 40 km.
Therefore, by taking this average of 40km and multiplying it by the surface area of Australia, the volume would come up to roughly 304,717,200 cubic km.
The diameter of Australia, measuring from East to West, is 4000km, making it wider than the moon along with a large number of the smaller moons and planets like Pluto.
Within this expansive continent is a collection of mountainous regions and ranges. The largest is the Great Dividing Range or the Eastern Highlands, which stretch 3,500km parallel to the East Coast.
Within the Great Dividing range lie the Australian Alps, a mountain range that is host to some of the highest peaks in the country, including Mount Kosciuszko, which is 2,228m high.
Fifty kilometers to the west of Sydney are the Blue Mountains, which are named for the blue haze filling the surrounding area. While these mountains are impressive, Australia has surprisingly few notable peaks considering its size. Instead, it has vast expanses of desert known as the Australian outback.
How Big Is Titan?
Titan is the largest of Saturn’s moons and the second largest satellite in our solar system (following Jupiter’s moon Ganymede). It is the only moon in the Milky Way that has clouds and a planet-like atmosphere.
Titan has a diameter of 5,150 km and a surface area of 83,000,000 sq. km. This surface area gives Titan an impressive volume of 71,600,000,000 cubic km.
This moon is so fascinating to scientists that they will launch the $1 billion drone “Dragonfly” to explore its surface. Titan has a thick atmosphere; because of this, the moon experiences a methane cycle of evaporation and condensation that creates rain, clouds, seas, and rivers. Other than Earth, Titan is the only body in the Milky Way that shows clear evidence of stable bodies of surface liquids.
The moon’s surface is one of the most Earth-like places in the Milky Way, though there are some vast differences. Firstly, the temperature is far, far colder, with an average surface temperature of −179.5 °C. And Titan’s gravity is only 14% of the Earth’s gravity, which means that a person weighing 100 kg on Earth will only weigh 14 kg on Titan.
Dutch astronomer Christiaan Huygens first discovered the moon in 1655 and named it Saturni Luna (Latin for “Saturn’s moon). It was in 1847 that English astronomer John Herschel suggested that the moon be renamed Titan from Greek mythology.
Scientists aren’t entirely sure about Titan’s origins but get some clues from its atmosphere. Instruments measuring the isotopes discovered that the ratio of Titan’s nitrogen isotope most closely resembles comets from the Oort Cloud – billions of icy bodies which orbit the Sun from a distance of 5,000 to 100,000 astronomical units.
This nitrogen ratio suggests that the moon was created from the same disc of dust and gas that formed the Sun.
Titan orbits at a distance of roughly 1.2 million kilometers from Saturn, a planet that is approximately 1.4 billion kilometers from the Sun. This vast distance means that sunlight takes around 80 minutes to reach Titan (compared to around eight minutes on Earth), and the light is 100 times fainter on this moon than we experience on Earth.
Summary
Australia is far from the biggest country on Earth whilst Titan is even bigger than Mercury so it makes sense that it absolutely dwarfs Australia
Mercury is over 10 times bigger in surface area and over 230 times Australia’s volume.
