- 1Real-time Solar System map tracks 526,000 asteroids●Show HN: Real-time Solar System with 526k asteroids and all tracked satellites
A developer has launched an interactive real-time simulation of the Solar System, plotting roughly 526,000 known asteroids alongside every tracked artificial satellite. The free web tool visualizes orbital positions as they are right now, letting users explore the crowded space environment around Earth and beyond. It is drawing attention on Hacker News, where commenters are praising the scale of the data and the smooth rendering in a browser.

Developers are discussing a technique for streaming charts where data changes every second. Instead of the costly route of rebuilding markup or redrawing a canvas on each tick, the approach uses st-core alongside CSS to update visualisations without re-rendering the DOM. Commenters in the open-source web development community are sharing the method as a lighter-weight option for real-time dashboards and monitoring tools.
