How far away is Comet Hale-Bopp from the sun? How far is the Earth from the Sun? What is the distance between Neptune and the sun? How far is the planet Pluto from the sun? How far are the gas planets from the Sun? What is the distance between the sun and Saturn?
The nearest known exoplanet orbits the starProxima Centauri, which is four light years away (~24 trillion miles). If a modern-day jet were to fly to this exoplanet it would not arrive for 5 million years. One of the most distant exoplanets is 3,000 light-years (17.6 quadrillion miles)...
Mercury, the closest planet to the sun, is about 0.39 AU from our star, while Neptune, the farthest planet from the sun, is 30.06 AU away from it. What's the difference between an astronomical unit and a parsec? An astronomical unit is the distance between Earth and the sun and ...
Kepler 62 is a 5-planet system about 1200 light-years away from Earth in the Lyra constellation. The host star is smaller and cooler than our sun. The first 3 planets closest to the sun are too hot and inhospitable. Next, is the planet Kepler 62f which is in the inner hospitable zone...
This exoplanet, the oldest ever detected in our Milky Way galaxy, has been nicknamed “Methuselah” or the “Genesis planet” on account of its extreme old age. Which is older Earth or Moon? The Moon is far older than we thought, new research has found. A new study, looking at lunar...
anywhere from a few light-years to a few billion light-years away. And everything astronomers "see" in the distant universe is literally history. When astronomers study objects that are far away, they are seeing light that shows the objects as they existed at the time that light left them...
one orbiting the nearest star to our solar system, proxima centauri. the planet, proxima b, orbits closely enough that its water might not be frozen (if it has water) and far enough away that it may not have baked off (maybe). the european space agency shared a surface view of a ...
But it also will depend on the distance to nearest Earth-like exoplanet. Located roughly 4.37 light years away, Alpha Centauri is the Sun’s closest neighbor; thus science fiction, including Star Trek, has envisioned it as humanity’s first interstellar destination. Read more...

Today, you’ve learned that the closest star to our own is Alpha Centauri. It’s moving closer to us. But not at an alarming rate. And finally, it has an exoplanet in the habitable zone of Proxima Centauri. Space is a remarkable place. We’re learning new things about it every day...
