Introduction. Astronomers have revealed the first photograph of an exoplanet taken by NASA’s James Webb Space Telescope (JWST). The image shows the bright blob of a world seven times heavier than Jupiter that orbits a star nearly 400 light-years away.
Can we travel to exoplanets?
Will a person ever go to an exoplanet? Not anytime soon, given the enormous distances between the stars and the time it would take to travel between them with our current technology. Perhaps one day a robot will visit an exoplanet like the rovers on Mars. But that day too is still very far in the future.
What is the closest exoplanet to Earth?
Distance, orbital parameters and age
Proxima Centauri b is the closest exoplanet to Earth, at a distance of about 4.2 ly. It orbits Proxima Centauri every 11.186 Earth days at a distance of about 0.049 au, over 20 times closer to Proxima Centauri than Earth is to the Sun.
