這是一個專為地球科學教學設計的互動式大數據探究工具,旨在幫助學生透過視覺化手段深入了解太陽系的動態結構。
- 自定義數據分析:使用者可自行上傳從 Minor Planet Center 網站下載的
MPCORB.DAT或是其他小行星、彗星的資料,並根據探究需求調整 X 軸與 Y 軸參數(如半長軸、離心率、軌道傾角、絕對星等)。 - 天體族群分類:內建自動分類算法,可呈現近地小行星 (NEA)、主小行星帶 (Main Belt)、特洛伊群 (Trojans) 及海王星外天體 (TNO) 的空間分佈。
- 專業級視覺化:整合 Plotly.js,支援上萬筆數據的流暢縮放、選取與即時資訊顯示。
- 隱私與效能:採純客戶端 (Client-side) 技術,數據在瀏覽器本地處理,不需上傳至伺服器。
- 從 MPC 官網 下載
MPCORB.DAT。 - 將檔案拖曳至網頁中。
- 透過下拉選單切換參數,觀察小行星的分類特性。
An interactive big-data exploration tool specifically designed for Earth Science education, helping students understand the dynamic structure of the Solar System through visualization.
- Custom Data Exploration: Upload your own Minor Planet Center asteroid orbital element data (
MPCORB.DAT) and adjust various parameters to visualize asteroid classifications. - Asteroid Classification: Features built-in algorithms to automatically categorize objects into Near-Earth Asteroids (NEA), Main Belt, Trojans, and Trans-Neptunian Objects (TNO).
- Professional Visualization: Integrated with Plotly.js to support smooth zooming, selection, and real-time hover info for tens of thousands of data points.
- Privacy & Performance: Powered by client-side technology. All data is processed locally in the browser, ensuring privacy and eliminating server latency.
- Download
MPCORB.DATfrom the official MPC website. - Drag and drop the file into the platform.
- Toggle different orbital elements and parameters to explore asteroid categories.
- Data Source: Minor Planet Center (MPC)
