It spent the next 11 years traveling in space and studying the surface and composition of both asteroids. The Dawn spacecraft traveled to Vesta and Ceres, the two largest objects in the asteroid belt. NASA's Dawn mission, launched in 2007, was one such endeavor. Thankfully, efforts are underway to track and monitor asteroids and understand their characteristics, which can help mitigate potential risks. However, a small number of larger asteroids could cause significant damage if they hit the Earth. An estimated 15,000 of them, broken down into meteorites, enter our atmosphere yearly. Most asteroids are relatively small and do not pose a significant threat to the Earth. These films allow audiences to consider the potential consequences of such an event in a fictional context.īut is it possible for an asteroid hit the Earth? And if one does, what do we do? Are we doomed to perish if an asteroid hits us, or do we already have the technology to defend our planet as they do in the movies? It is the difference between the measured value and “true” value,The Mean Absolute Error(MAE) is the average of all absolute errors.The prospect of an asteroid hitting the Earth is a genuine concern for many scientists and policymakers. Mean Absolute Error: Absolute Error is the amount of error in your measurements.The lower the MSE, the better the forecast. It’s called the mean squared error as you’re finding the average of a set of errors. It also gives more weight to larger differences. The squaring is necessary to remove any negative signs. It does this by taking the distances from the points to the regression line (these distances are the “errors”) and squaring them. Mean Squared Error: The mean squared error (MSE) tells you how close a regression line is to a set of points.It is also known as the coefficient of determination, or the coefficient of multiple determination for multiple regression. R2 score: R-squared is a statistical measure of how close the data are to the fitted regression line.I have used the various models for predicting the asteroid diameter Metrics used Inclination with respect to x-y ecliptic plane(deg)Įxploratory Data Analysis Loading the Dataįrom the following figure we are able to infer the relation between data_arc and no of observations, we can state that most of the asteroids are in the arc-data with less number of outliers Machine Learning Models.But in the following Dataset,iam only considering some of the important features In this dataset we are provided with the information about the various asteroids and their orbital velocities and diameters and magnitudes and many other features, The following dataset has been taken from Kaggle which has been taken from Nasa’s JPL database, you can find the link to the dataset here, It is a very large dataset that consists of about 8Lakh tuples and 27 columns. So we are concerned with finding the right method to estimate the diameter of asteroid as it is the physical diameter of Asteroid,By estimating the method we can reduce the damage even if a asteroid is going to hit the earth. So in order to prevent the damage caused by asteroid we can use Machine Learning to predict the diameter of asteroid.Īs Asteroids are small rocky objects that revolve around the sun, We are mainly concerned with the estimation of asteroid diameter, But actually the prediction of asteroid diameter is not an easy job because there are many methods to estimate the diameter of asteroid and every method is trying to surpass the previous one. Impact conditions such as asteroid size and speed, but also density and impact angle determine the kinetic energy released in an impact event causes the asteroid to hit the earth. The most probable impact angle is 45 degrees. Before getting deeper in to the project let us have a quick overview what an asteroid means really?Īsteroids are small rocky objects that revolve around the sun like planets, Even though they orbit around the sun just like our planets do they are much smaller than our planets, There are millions of Asteroids but most of them mainly live in the Asteroid belt where it lies between mars and Jupiter.ĭue to Earth’s escape velocity, the minimum impact velocity is 11 km/s with asteroid impacts averaging around 17 km/s on the Earth. So we are concerned in predicting the diameter of asteroid because if we can estimate the diameter of Asteroid, We can estimate the amount of damage that can be caused by the asteroid if it hits the earth. If it hits the earth this blow could possibly destroy a entire city. Ever Wondered What if an Asteroid that is as huge as size of the apartment hits the Earth.
