Space Tools

Free browser space tools that read live public data. Track near-Earth asteroids making close approaches from NASA/JPL data, watch the International Space Station cross a world map in real time, and explore the deep sky with an interactive star map. No sign-up, no API key.

Free

Asteroid Tracker

Near-Earth asteroids passing close to us, from NASA/JPL close-approach data — size estimate, speed, miss distance in lunar distances, and when. Flags any inside the Moon's orbit.

Open tool Free

ISS Tracker

The International Space Station's live position on a world map, with its ground track, altitude and speed — refreshed every few seconds from open orbital data. Pure browser, no tiles.

Open tool Free

Sky Explorer

Pan and zoom across the real night sky — stars, galaxies and nebulae from professional survey imagery (DSS, 2MASS). Powered by Aladin Lite, jump to famous objects.

Open tool

Three Windows on Space

Each tool reads a live public feed and shows it plainly — no account, no key.

1

See what's passing by

Open the Asteroid Tracker for the near-Earth asteroids approaching us over the coming weeks — sorted by date, with miss distance in lunar distances and a size estimate.

2

Follow the station

Open the ISS Tracker to watch the International Space Station orbit Earth roughly every 90 minutes, with its live latitude, longitude, altitude and speed.

3

Explore the deep sky

Open the Sky Explorer to pan and zoom across real survey imagery — galaxies, nebulae and star fields — then plan a clear night with the LK Forge Moon Phase and Sun Times tools.

Frequently Asked Questions

What is the LK Forge Space suite?
A set of free, browser-based space tools. The Asteroid Tracker lists near-Earth asteroids making close approaches using NASA/JPL CNEOS data; the ISS Tracker shows the live position of the International Space Station on a world map from the open wheretheiss.at feed. Both are free, no sign-up, no API key.
Where does the data come from?
Asteroid close approaches come from NASA's Jet Propulsion Laboratory (JPL) CNEOS Close-Approach Data API. The ISS position comes from the open wheretheiss.at API, derived from public orbital data. LK Forge presents these public feeds — it does not track or measure anything itself.
Is the asteroid tracker a warning system?
No. It shows close approaches astronomers have already computed from each object's orbit — for curiosity and learning, not hazard warnings. For authoritative near-Earth-object information see NASA CNEOS and the Planetary Defense Coordination Office.
