Rather than being a planet or a star, the moon is a natural satellite that orbits the Earth. The Moon Is A Natural Satellite A view of the Earth and Moon in space. This is a fancy way of saying that it glows or burns, like our sun. A star is usually defined as a body of gas which is large enough and dense enough that the heat and crushing pressure at its center produces nuclear fusion. The Earth is an example of a planet and orbits the sun, which is a star. We have found stars that are 100 times bigger in diameter than our sun. There are bigger stars, and there are smaller stars. The size of our sun It turns out that our Sun is an average sized star.

Now we have only eight planets as pluto is excluded. There were nine planets in the solar system, Which are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. Taking the Moon’s Temperature Daytime temperatures near the lunar equator reach a boiling 250 degrees Fahrenheit (120° C, 400 K), while nighttime temperatures get to a chilly -208 degrees Fahrenheit (-130° C, 140 K). That said, there is actually plenty of oxygen on the Moon. It’s not the sort of gaseous mixture that could sustain oxygen-dependent mammals such as humans. …Īlthough the Moon does have an atmosphere, it’s very thin and composed mostly of hydrogen, neon and argon. The Moon makes the Earth move as well as the tides.The Moon was made when a rock smashed into Earth.The Moon is drifting away from the Earth.From Earth, both the Sun and the Moon look about same size. The Sun and the Moon are not the same size.It would move from no tilt (which means no seasons) to a large tilt (which means extreme weather and even ice ages). Without the Moon stabilising our tilt, it is possible that the Earth’s tilt could vary wildly. See also What Is The Purpose Of The Hadron Collider In Switzerland What if we had no moon? In Latin, the Moon is called Luna, which is the main adjective for all things Moon-related: lunar. What is Earth’s moon called?Įarth’s only natural satellite is simply called “the Moon” because people didn’t know other moons existed until Galileo Galilei discovered four moons orbiting Jupiter in 1610. Now, astronomer Jason Barnes says that life on our planet would endure even without a moon, a finding that might increase the number of potentially habitable planets in our galaxy. And as the Sun’s core becomes saturated with this helium, it shrinks, causing nuclear fusion reactions to speed up – which means that the Sun spits out more energy. In fact, it burns through 600 million tons of hydrogen every second. The Sun survives by burning hydrogen atoms into helium atoms in its core. Venus is the exception, as its proximity to the Sun, and its dense atmosphere make it our solar system’s hottest planet. Planetary surface temperatures tend to get colder the farther a planet is from the Sun. It comes from the Old English words ‘eor(th)e’ and ‘ertha’. The name Earth is an English/German name which simply means the ground. Who named Earth?Īll of the planets, except for Earth, were named after Greek and Roman gods and godesses. Like the Earth, our moon has a crust, a mantle and a core. But did you know our moon functions like a planet? It has a lot to teach us about how planets form and evolve. The IAU definition also excludes moons from being planets. The below mentioned requirements disqualify the moon from being referred to as a planet. The star which is the formation of hot gasses, energy, light and heat, which doesn’t refer to the moon’s qualities. Star which does not consist of solid material like the moon.

A satellite is a generic term for an object that orbits another object. Is the Moon a planet? Well, not really, as a planet is an object that orbits a star, and the Moon orbits the Earth (and yes, wannabe pedants, it really does orbit the Earth and not the Sun). The Sun is about 93 million miles (150 million kilometers) from Earth, and without its energy, life as we know it could not exist here on our home planet. Our Sun is a 4.5 billion-year-old star – a hot glowing ball of hydrogen and helium at the center of our solar system. The moon’s core has never ignited, so it does not fall under the definition of a star. To be a star, a celestial body must be capable of igniting itself because of its mass. While it shines just like many of the stars in the sky, its light comes from the sun, not itself. In reality, the moon is not considered a star.
