- At 11.2 billion years old, it is the oldest star with Earth-sized planets ever found and proves that such planets have formed throughout the history of the Universe.
- The star, named Kepler-444, hosts five planets smaller than Earth, with sizes varying between those of Mercury and Venus.
- This tells us that planets this size have formed for most of the history of the universe and we are much better placed to understand exactly when this began happening.
