简介 440光年. 穿越它需要：

• 光440年
• 旅行者1号的速度7.82百万年
• 以100 km/h的速度行驶4.75亿年

旅行者1号以截至2026-10-25的一年中向外运动的速度（JPL Horizons）。驾车：不停歇，永不加油。

发现方式

• 2025年通过直接成像法发现首颗行星（NASA系外行星档案库）。

它的行星

• WISPIT 2 b — 18 times Earth's width, a giant, Jupiter-sized or more; about −240 °C, below freezing; found in 2025 by imaging.
• WISPIT 2 c — 18 times Earth's width, a giant, Jupiter-sized or more; about 1,800 °C, hot enough to melt rock; found in 2026 by imaging.
