Uranus orbit
Fly around Uranus aboard the castle rocket. Admire pale blue-green clouds, soft polar haze and narrow dark rings tilted with its 97.77-degree spin axis. Cruise outside the faint outer dust rings, switch between cabin, outside and aerial views, pause, and return to Hong Kong when ready. Uranus is an ice giant without a solid landing surface. Body and ring radii share a physical scale; travel, rotation, cloud patterns, ring widths and contrast are illustrative; the separate overview uses a fixed dated calculation.
What can I do here?
View a pale blue-green globe, soft polar haze and narrow dark rings aligned with the planet’s sideways spin axis. Stay outside the rings and choose cabin, exterior or overview views.
Can I land, walk and deploy a rover?
No. This is an orbit or cruise experience, with no surface walk or rover. Observe the scene from cabin, exterior and overview views.
How do I control the journey and return?
Use the bottom controls to switch views, pause or reset the view. Drive the rover with WASD or arrow keys and hold the left mouse button to look around; touch controls are available on phones.
The journey stays at the destination until you choose Return to Earth. During surface exploration, use the collect/return controls to bring the rover back before departure.
How do I use the telescope and take photos?
Switch to the rocket cabin and open the telescope. Hold the left mouse button to drag or use WASD to aim. Q zooms out, E zooms in; the wheel and on-screen buttons also work. Press Space or the photo button to capture the current view, then download a PNG or use sharing supported by your device. Esc closes the telescope.
Choose an available celestial body from Track target to keep it centred as it moves, then adjust magnification from 1–100×. A View obstructed message means another body blocks the sightline; tracking does not see through it.
Drag, use WASD or the direction controls, or choose Manual aim to release tracking while keeping the current direction and magnification. Reset telescope restores the initial direction and 1×. Photos work in both tracking and manual modes.
Astronomy background
Uranus is an ice giant with an axial tilt of about 98 degrees and a ring system. It has no solid surface suitable for a conventional landing.
What is fictional?
Cloud detail, rotation speed, haze and ring visibility are artistic. Ice giant describes the planet’s composition, not a walkable surface of ice.
Are the positions live?
The solar-system overview and navigation map use Astronomy Engine to calculate positions for the date and time captured when the world opens. This fixed snapshot is not continuously refreshed. Display distances are compressed; local terrain, spacecraft routes, cloud patterns and most moon animations are illustrative. Dashboard speed and Earth distance describe the simulated journey, not a real spacecraft.

環繞天王星
乘坐城堡火箭環繞天王星，欣賞淡藍綠色雲層、柔和極區霧氣，同隨 97.77 度自轉軸一齊側躺嘅窄暗環。航道設喺微弱外層塵埃環之外，可切換艙內、艙外同俯瞰、暫停，準備好先返回香港。天王星係冰巨星，冇可降落漫步嘅固體表面。星球及星環半徑共用實際比例；航程、自轉、雲層、環寬及對比屬藝術演繹，當地場景屬示意，獨立俯瞰則使用按日期計算嘅固定位置。
可以玩啲咩？
欣賞淡藍綠球體、柔和極區霧氣，同隨側躺自轉軸傾斜嘅窄暗環；航道位於星環之外，可切換艙內、艙外或俯瞰。
可以登陸、漫步同放車仔嗎？
唔可以。呢段係環繞或航行體驗，冇地面漫步或探測車；可從艙內、艙外及俯瞰欣賞場景。
點樣操作同返地球？
用下面控制條切換視角、暫停或重設視角。駕駛探測車時使用 WASD／方向鍵，按住左鍵拖曳環視；手機可用畫面控制。
旅程會停留喺目的地，直到你選擇「返回地球」。地面探索時先用收車／返回控制收回探測車，再開始返航。
望遠鏡點用？可以影相嗎？
切換到火箭艙內再打開望遠鏡。按住左鍵拖曳或用 WASD 瞄準；Q 縮小、E 放大，亦可用滾輪或畫面按鈕。按 Space 或影相制擷取目前視角，預覽後可下載 PNG 或使用裝置支援嘅分享功能；Esc 關閉望遠鏡。
用「追蹤目標」選單揀目前場景可用嘅行星或衛星，望遠鏡會跟住目標並保持佢喺中央，再喺 1–100× 範圍調整倍率。如果顯示「視線受遮擋」，代表有天體擋住視線，追蹤唔會穿透遮擋。
拖曳、按 WASD／方向控制，或者選「手動瞄準」會解除追蹤，保留目前方向同倍率；「重設望遠鏡」會返回初始方向及 1×。可喺追蹤或手動模式影相。
科學背景
天王星係有星環嘅冰巨星，自轉軸傾角約 98 度，冇適合一般登陸嘅固體表面。
邊啲係幻想設定？
雲層細節、自轉速度、霧氣同星環可見度均屬藝術演繹。「冰巨星」描述行星成分，唔代表有可步行嘅冰面。
位置係實時嗎？
太陽系俯瞰同導航小地圖使用 Astronomy Engine，按開啟世界時記錄嘅日期與時間計算天體位置；此固定快照唔會持續更新。顯示距離經壓縮，當地地形、飛船航線、雲紋同大部分衛星動畫均屬示意。儀表航速同地球距離描述模擬旅程，並非真實航天器。
