Welcome to SkyDecay

SkyDecay is dedicated to tracking and notifying users about fascinating astronomical events.
Our main focus is on satellite re-entries, but i will also provide notifications about
supernovae explosions, comets, solar storms and more

How It Works

The website operates on a hosting platform, while the main code, written in Python, runs on a local machine. At adaptive intervals, data on satellite re-entries is retrieved from Space-Track or other online databases for other kind of events, processed, and possibly notified. Notifications are managed through Telegram bots that users can create and register on the site. Telegram bots provide an efficient and simple way to facilitate communication between the website and users while minimizing the exposure of personal data such as passwords or email addresses. All that is required is your location (even approximate) and the token of the bot you create.

Features

• Decaying: A table showing satellites with imminent re-entries.
• Decayed (under development): Statistics on already decayed satellites.
• IMO Detector (under development): Information about satellite decays whose trails have been identified by the International Meteor Organization.
• NEO Impact Risk (under development): More and more near-Earth orbit asteroids are being discovered, and sometimes one is found just hours before its impact with Earth.
• Bright SN (under development): Notable SN or Novae events
• Bright Comets (under development): When the magnitude of a comet become low enought to be potentially visible to naked eye
• Solar Storms (under development):A solar storm could be powerful enough to generate auroral events at low latitudes, events you don't want to miss.

Please note that the website is still under development, and some features are not available yet. Stay tuned for updates as i continue to improve the platform!

Orbital Decay

Most artificial satellites in Low Earth Orbit (LEO) tend to gradually lose altitude if not actively controlled. This is mainly due to two factors: the Earth’s non-spherical shape and atmospheric drag.

In some cases, satellite re-entry is conducted in a controlled manner, ensuring that any debris falls in low-risk areas, minimizing danger to people or property. However, in other cases, re-entry is completely uncontrolled, meaning the object could re-entry to any point on the planet within the limits of the satellite’s orbital inclination. While the risk of causing damage is minimal even in uncontrolled scenarios (case of damage), with a bit of luck, it’s possible to witness the spectacular event of atmospheric re-entry (watch the video).

Although the chance of harm from a re-entry is very low, real-time monitoring of these events is crucial. This need arises from the ever-growing number of satellites in orbit and the importance of validating the models used for prediction.
