Earth shape bulges at the equator and flattens at the north and south pole. Planet Earth has an abundance of water that makes it unique and perfect for life to exist. Our actions in the next decade will determine our collective path forward. A look at the origins of our planet reveals a chaotic time as far back as we can imagine. We use the core accretion model to describe planet formation and the creation of our solar system which includes a central star and natural orbiting objects. In fact, it’s in the shape of an oblate spheroid. Earth is unique in that scientists have found the planet to be the only one to have liquid water on its surface, intelligent life forms living on it, a moon that helps regulate surface temperatures, an atmosphere with 21 percent oxygen and plate tectonics, according to All of the sudden, Earth starts looking small. Shape of the Earth: The Oblate Spheroid Outer Space Earth is not a perfect sphere. Meaning that Earth makes up about 0.0003% of the total mass of our solar system. Planet Earth is called the "Goldilocks planet." Our Future on Earth 2020 aims to tell the story of where we are on our collective journey by connecting the dots between what society is currently experiencing – from fires to food shortages to a rise in populism – with recent developments in the research community. If the earth age dates to this period, exactly how did the earth form? Scientists believe Earth exists in a "Goldilocks zone" where conditions are just right to support life. No great push to embrace radiometric dating followed, however, and the die-hards in the geological community stubbornly resisted. The total mass of the solar system is about 333,345.997 Earth masses.

These events eventually settled, and luckily for us, life began to develop and prosper everywhere across the globe. Find out why it is just right for us! Holmes published The Age of the Earth, an Introduction to Geological Ideas in 1927 in which he presented a range of 1.6 to 3.0 billion years.
