SOLAR NEBULA/BIRTH OF SUN
The sun and planets all formed from a cloud of gas known as the solar nebula. The formation of the solar nebula was prompted by the nearby explosion of a supernova, as proven by the traces of nickel 60, the decay product of iron 60, found in the meteorites that have fallen onto earth's surface. Iron 60 can only come from one place: a supernova, and meteorites are simply asteroids that have descended upon earth; these asteroids have existed since the genesis of our solar system. The traces of nickel found in the meteorites proves that the solar nebula was formed due to the impact from a nearby supernova. The wave of pressure from the supernova made the solar nebula collapse and condense, or essentially flatten. The solar nebula led to the creation of a protostar that became our sun, and the planets orbited around our sun in a thin disk. |

ACCRETION OF PLANETESIMALS
The accretion of planetesimals was the formation of planets. Planetesimals were spherical masses that later became planets. Planetesimals started as disks of dust and rocks surrounding the sun. As dust particles clumped together, planetesimals formed along with planetary embryos. Planetesimals were the early stages of protoplanets that later became the planets we know today. Planetesimals were tens and hundreds of thousands of kilometers large, and planetary embryos were about the size of the moon or Mars. As planetesimals grew larger, their gravitational pull also increased. This led to their expansion to protoplanets and eventually planets. Planetesimals that didn't become protoplanets instead became asteroids. This led to the formation of the asteroid belt. Planetesimals that did become planets migrated into orbit around the sun due to the sun's gravitational pull. The complete formation of the terrestrial planets is confirmed to have been completed 100-200 million years ago, thanks to radiometric dating and numerical simulations. Proof of this process is the measurements and simulations made of the physics of planetesimal collisions and dust, including chondrules. Chondrules include tiny rocks and dust from both before and after the formation of planets and planetesimals. Chondrules survived on meteorites. |

FORMATION OF MOON
The formation of the moon is a topic of debate. There are multiple theories, including the Fission Theory, Capture Theory, and Coformation Theory. The most supported theory, however, includes a protoplanet named Theia. Theia was a protoplanet roughly the size of Mars. Theia collided with Proto-Earth and ended up crushing itself. The debris from the impact stayed in Earth's orbit and became the moon. This collision happened 60-175 years after the solar system was formed. This theory has the most evidence supporting it, including oxygen samples. Oxygen isotope samples from the moon were retrieved and compared to the oxygen isotopes of the Earth. There were many similarities. The moon also has many craters and flattenings on its surface that match the materials found on Earth. |

LATE HEAVY BOMBARDMENT
Around 4 billion years ago, our inner solar system, including the inner planets, suffered from a series of pummeling asteroids that carved giant basins and clearings into our moon from the impact. The asteroid belt had fallen into disarray because the gas giants had suddenly changed their orbits, and this sent the asteroids towards the inner planets. The scarred surfaces of the Moon, Mercury, and Venus, the distribution of asteroids in the asteroid belt, and moon rocks with the dates of impact melt into them are all scientific evidence for the late heavy bombardment. There is still debate today about whether the late heavy bombardment happened at all, as some argue there aren't enough samples from the moon for this theory to be probable, on top of the moon's samples being difficult to date. The late heavy bombardment certainly isn't a concrete event in our solar system's history. |

DIFFERENTIATION OF EARTH'S LAYERS
The main differentiation of Earth's layers is their chemical makeup. There are three main layers of the Earth. There is the core, mantle, and crust. The core is made up of mostly iron, with the innermost core made of iron-nickel alloy. The core is the center of Earth and the hottest part of Earth. The second layer of Earth is the mantle. The Earth's mantle is mainly peridotite. Finally, Earth's crust is made mainly of granite and is the surface layer of Earth. The crust is where most of Earth's different materials are, including the oldest known mineral, zircon. We are able to find out about the Earth's layers by measuring the speeds of seismic waves that penetrate and pass through the Earth's core. It is believed that Earth's layers started to differentiate around the formation of Earth itself, around 4.6 billion years ago. |

CONTINENTAL CRUST FORMS
We can use experimental results to place the time of primitive plate tectonic formations in the Eoarchaean period. One of the most supported theories of the formation of the continental crust is that it formed in volcanic arches. Another theory is that debris from when Theia hit the Earth was recycled into the continental crust. It is believed that continental crust was formed after magma from Earth's core rose to the surface and cooled to form solid land. After weathering and erosion over billions of years, Earth's continental crust became what we know today. As Earth's crust formed, so did its plate tectonics. The plate tectonics broke up the crust into pieces that overlap and sometimes grind against each other. This leads to the formation of things like mountains and trenches. |

CONTINENTS AND OTHER GEOLOGIC FEATURES BEGIN TO FORM AND CHANGE |
The very first continent was Ur, formed around 3 billion years ago, followed by Arctica, forming 2.5 billion years ago. Baltica and Atlantica then emerged a half billion years later. Arctica and Baltica then collided with current day eastern Antarctica to form Nena, another continent. Then, one billion years ago, all of the continents fused together to make our first supercontinent, Rodinia. After 300 million years of being together, and then 400 million years of having broken apart and drifted, the continents then fused back together as Pangea.

The Solar System's Blurbs
About me:
One of our solar system's most famous failed planetesimals is Vesta. Vesta is special because it is the second-largest mass in the asteroid belt. Unlike other failed planetesimals that became asteroids, Vesta has layers like the Earth. Vesta has a crust, mantle, and surface.
