The host star formed 11 billion years ago, when the universe was less than 20 percent of its current age. This makes Kepler-444 the oldest known system of terrestrial size planets. The star has a companion binary that gets as close as 5 AU at periastron. Link to scientific paper Your name Note: Your commit will be vetted before it is merged into the public version.
