Shooting Stars are a marvel that many are raised to believe are a rare and almost supernatural event.
It's turns out however that these balls of fire in the sky, are not as rare as many
This project was created partially as a response to that.
It's purpose is to delve in to the data of fireballs and meteorites, to provide a more realistic expectation of these cosmic occurances and provide insight as to the locations on Earth that have the most impacts and how much thtat impact will affect the surrounding area.
The first step in the process was deciding on tasks and asking questions to be found during this
- Find hotspots for meteorite impacts
- Calculate impact crater size
- What time of year has the most impacts?
- What is the average mass of meteors?
- Are there more impacts around the equators or the poles?
- How many meteors fell in important years (birth year(1995), Y2K, 2008(Obama), 2020(Now)?
I started by conducting EDA (Exploratory Data Analysis) on the NASA Meteorite dataset using the Python language and Jupyter Notebook, a popular tool for data science. The data contained approx. 46,000 rows of data including: unique names, meteor classifications, locations, fall vs. fallen, and mass.
At this point I realized that one dataset was not going to be sufficient, so I found and used the IMO dataset to take a different perspective.
While it did contain less unique meteorite data (approx. 43,000), it did contain information including: Observer ID, Report date, location, and elevation. This allowed for a comparison between the 2 datasets and also to explore other perspectives.
Once the 23 datasets were analysed on a basic level, the process of answering the questions began. The main 2 focuses on figuring out the size of hte impact crater and to find any pattern sin the geolocation and time of year.
Every project contains a certain level of error and unexpected difficulties.
The first problem was to find the formulas for the impact crater.
- The proceess began off simply (see formulas here), but the
main issue came up when the Cosmic Velocity (speed) needed to be found. That number is
crucial for calculating the Final Velocity (vf) and Kinetic Energy (KE) of meteors above
a certain size.
- My research was not asble to find or calucate a certain, or agreed upon number, so the
impact velocity is currently not calucated.
The second main problem noticing many of the locations from the NASA centers themselves.
- While this does still show a certain level of location data, the meteors that were observed falling (fall) were given the location of the center in while it was seen.
- The way of handling this was to take in another dataset to compare location data.
- Also realizing that the meteors that are seen falling in the sky cannot have a exact location, so their locations can only be approximate.
