1 gigayear = 1,000,000,000 years
We'd probably use the term 1 gigayear to mean 1 billion years (in the U.S.). The prefix "giga" means 1,000,000,000 or, if you prefer, 106 units of something. The gigayear is a billion years, just the the gigaHertz is a billion Hertz (or cycles per second). Also note that we use a "big" G to represent giga. A Gyear is a gigayear or a billion years.Many consider an Eon to be a billion years
A year on Mercury is only 88 Earth days. Mercury is the closest planet to the Sun and has a very short orbital period, causing its year to be much shorter compared to Earth's year of 365 days.
A year on the moon is about 27.3 Earth days long, as it takes that amount of time for the moon to complete one orbit around the Earth. This is shorter than a year on Earth, which is about 365.25 days long.
Australia has about 80 tornadoes every year.
Jupiter has around 10 hours shorter day compared to Earth. It revolves around the sun once in about 11.86 Earth years. So, a year on Jupiter is roughly equivalent to 4,332 Earth days.
Gigayear. The early Earth is loosely defined as Earth in its first one billion years, or gigayear (Ga, 109y). The “early Earth” encompasses approximately the first gigayear in the evolution of our planet, from its initial formation in the young Solar System at about 4.55 Ga to sometime in the Archean eon at about 3.5 Ga.
It COULD be called a Gigayear, but in practice it is simply called "a billion years".

The prefix "giga" means 10 to the 9 or 1 billion.
Astronomers use g years as an abbreviation for gigayear. Specifically, one Gyr is equal to 109years, or a billion years.
Compared to Earth, Mercury has a very fast year. It is 88 Earth days compared to Earth's 365.25 days.
