Astronomers You Must Know

(If You Care About Rogue Planets, Cosmic Catastrophes, and the Drama of the Heavens)

If you’re serious about understanding how a rogue planet might disrupt the solar system—and how scientists like my fictional characters David Mitchell and Manny Volynsky would argue over such events—then you must be familiar with certain towering figures in the history of astronomy. These are the thinkers whose insights shape the way we interpret celestial mechanics, orbital dynamics, and cosmic disruption.

Below is a concise guide to 10 astronomers whose work would be required reading for anyone engaged in conversations like those unfolding in Red Sky.


1. Johannes Kepler (1571–1630)

Why he matters:
Kepler’s Three Laws of Planetary Motion remain the bedrock for understanding how planets move around stars. In Red Sky, both David and Manny would constantly reference Kepler’s elliptical orbits, especially as they debate whether the rogue planet’s path can intersect Earth’s orbit without violating known celestial mechanics. Without Kepler, there is no predictive model of orbital interaction.


2. Isaac Newton (1643–1727)

Why he matters:
Newton expanded Kepler’s observational laws into a universal mathematical framework. His law of universal gravitation explains how a rogue planet’s mass would gravitationally interact with Earth, the Moon, and the entire solar system. Newton’s equations would be used in every simulation David’s team would run as the intruder approached.


3. Edmond Halley (1656–1742)

Why he matters:
Halley demonstrated that comets return in predictable cycles. This is crucial for understanding that some bodies on highly elongated orbits may periodically enter the inner solar system—exactly the kind of behavior our rogue planet might display. His predictive work on periodic comets directly parallels the orbital questions posed in Red Sky.


4. William Herschel (1738–1822)

Why he matters:
Herschel’s discovery of Uranus and his deep-sky surveys expanded humanity’s awareness of the solar system and beyond. He demonstrated that unexpected planetary bodies could exist undetected until they cross our view—exactly the situation with a rogue planet suddenly entering Earth’s vicinity.


5. Carl Sagan (1934–1996)

Why he matters:
While not a discoverer of planets, Sagan’s work in planetary atmospheres (notably Venus), public science communication, and the hazards of planetary impacts (he was among the first to highlight nuclear winter scenarios) make him directly relevant. Manny would see Sagan’s warnings about global catastrophe as prophetic echoes of his own dire predictions.


6. Christiaan Huygens (1629–1695)

Why he matters:
Huygens pioneered early wave theory of light, refined telescopic optics, and discovered Saturn’s largest moon, Titan. His work would serve as foundation for observational techniques used to study the rogue object’s composition and behavior.


7. Edwin Hubble (1889–1953)

Why he matters:
Hubble’s discovery of the expanding universe fundamentally changed humanity’s understanding of cosmic scale. While not directly involved in planetary motion, his extragalactic perspective serves as a philosophical counterweight in Red Sky—reminding both Manny and David how small the solar system is in the grand scheme, yet how devastating local disruptions can be.


8. Frank Drake (1930–2022)

Why he matters:
Creator of the Drake Equation, Drake’s work on the likelihood of extraterrestrial civilizations also touched on planetary formation and system stability. For Manny, Drake’s probabilistic thinking would support the idea that rogue planetary events—though rare—are entirely within the realm of cosmic possibility.


9. Clyde Tombaugh (1906–1997)

Why he matters:
Tombaugh’s discovery of Pluto (and later, the Kuiper Belt) opened the door to understanding that many icy bodies exist on the edges of the solar system, some with unstable orbits. The rogue planet in Red Sky might well have originated from such a region—a displaced object, not unlike Pluto, but far more dangerous.


10. Immanuel Velikovsky (1895–1979)

Why he matters (for Manny):
While rejected by mainstream science, Velikovsky’s radical catastrophism deeply influences Manny Volynsky’s thinking. His claim that planets have shifted orbits in historical times, and that Venus and Mars once made catastrophic near passes to Earth, resonates strongly with Red Sky’s central premise. David would dismiss Velikovsky as pseudoscience, but Manny sees his theories as a lost key to forgotten cosmic events.


Final Thoughts

If you’re following the debate between David Mitchell and Manny Volynsky in Red Sky, these are the intellectual ancestors hovering in the background of every heated discussion. Some are icons of established science; others remain deeply controversial. But together, they form the scaffolding for any serious consideration of rogue planetary intrusion—and the fragile stability of our cosmic home.
