The Sky Above Theodore Roosevelt at the Moment of Death

Person · 1858–1919 · Approximate time

The record

• Date of death: 1919-01-06
• Time of death (local): 04:15 (Approximate time) — He died in his sleep unattended; the 1919 wire copy states 4:15 a.m. was "as nearly as can be determined", and some contemporary reprints said only "about 4 o'clock".
• Place: Oyster Bay (Sagamore Hill), New York, United States
• UTC: 1919-01-06T09:15Z

The sky at that moment

• Zenith (the point directly overhead): RA 171.22°, Dec 40.42°

Star closest to the zenith

Computed with the same standard astronomy as our free calculator: the recorded time and place give the local sidereal time, which fixes the zenith; the closest star by angular distance inside a ±15° declination band of the real catalog is selected. What is shown here is the purely astronomical result — the nearest star to the zenith.

• Catalog ID: HIP 55587
• Constellation: Ursa Major
• Magnitude: 9.38
• Distance (light-years): 726.4
• Angular distance from zenith (degrees): 0.3930°

Brightest stars in that sky

The brightest real stars (catalog IDs from the HYG star catalog — mostly Hipparcos/HIP numbers) that were above 10° altitude at that same moment.

• HIP 91262 — Lyra, Magnitude 0.03 (12.5°)
• HIP 24608 — Auriga, Magnitude 0.08 (27.5°)
• HIP 37279 — Canis Minor, Magnitude 0.4 (29.2°)
• HIP 27989 — Orion, Magnitude 0.45 (11.4°)
• HYG 118360 — Auriga, Magnitude 0.96 (27.5°)

人物 · 1858–1919 · 时刻为约数

记录

• 离世日期: 1919-01-06
• 离世时刻(当地): 04:15 (时刻为约数) — 睡梦中离世、当时无人陪床;1919 年电讯稿称 4:15 只是「大致所能确定」的时刻,另有当时的转载仅作「约 4 点」。
• 地点: 纽约州牡蛎湾(萨加莫尔山), 美国
• 世界时(UTC): 1919-01-06T09:15Z

那一刻的星空

• 天顶(正头顶的那一点): RA 171.22°, Dec 40.42°

离天顶最近的星

与站内免费计算器同一套标准天文算法:由记录的时刻与地点推出当地恒星时,得到天顶坐标,再取真实星表里赤纬 ±15° 带内球面角距最小的星。这里给出的是「离天顶最近」这一纯天文结果。

• 星表编号: HIP 55587
• 星座: 大熊座
• 星等: 9.38
• 距离(光年): 726.4
• 与天顶的角距(度): 0.3930°

那一刻天空中最亮的星

同一时刻位于地平线 10° 以上、星等最亮的前几颗真实恒星(HYG 星表编号,多为 Hipparcos/HIP 编号)。

• HIP 91262 — 天琴座, 星等 0.03 (12.5°)
• HIP 24608 — 御夫座, 星等 0.08 (27.5°)
• HIP 37279 — 小犬座, 星等 0.4 (29.2°)
• HIP 27989 — 猎户座, 星等 0.45 (11.4°)
• HYG 118360 — 御夫座, 星等 0.96 (27.5°)
