Near Earth Object Tracker

A daily tracker for asteroids and comets whose orbits bring them close to Earth, pulled live from NASA.

This web app retrieves and displays information about Near Earth Objects — asteroids and comets on orbits that pass close to Earth’s. It fetches the day’s NEO data and presents it in a form you can actually read.

What it shows

  • Object IDs and names.
  • Hazardous status.
  • Close approach dates.
  • Current and past orbiting bodies.
  • Maximum and minimum diameters, in metres and feet.
  • Velocity, in km/h and mph.
  • Orbit classification with descriptions.
  • First and last observation dates.

How it is built

Full-stack Python on Flask, hosted on Vercel. There is no database: data is pulled directly from the NASA API on request, and DataTables renders it as a searchable, sortable table.
