Strange giant planet TOI-1355 b set to vanish from view in 2033
Astronomers have identified a hot Jupiter exoplanet, TOI-1355 b, whose eccentric orbit is expected to shift within a decade, potentially making it invisible to current transit observation methods. This discovery provides new insights into the orbital evolution and gravitational dynamics of exoplanetary systems.
Why it matters
Understanding the transient nature of exoplanet visibility helps refine models of planetary system architecture and evolution.
Since their first discovery in 1995, hot Jupiter exoplanets (hot Jupiters, for short) quickly challenged our understanding of exoplanet formation and evolution, including exoplanetary system architecture. This is because, as their name implies, they orbit at extremely close distances to their host stars, ranging from a few days to a few hours. Some of their orbits are even oval-shaped, called eccentric in the scientific community, meaning their orbit is oval-shaped. But could such an orbit cause a hot Jupiter to completely vanish from view, preventing astronomers from studying it?
