The distant solar system reveals “what our solar system will look like after the disappearance of the Earth”
Astronomers have discovered a planetary system that resembles how our solar system will look long after the sun dies. The system consists of a large gas giant, similar to Jupiter, orbiting a dead white dwarf star.
While there’s no pinpointing an exact date and time when our solar system arrived on the premises, the good people at NASA have given a ballpark estimate of 4.5 billion years.
There’s a lot we haven’t learned about the quarter-mile-long object since its discovery in 2017.
To answer this question, we have to go back in time.
Our solar system is filled with everything from planets to rocky asteroids to small icy bodies beyond Pluto, but surrounding all of it is a diffuse halo of objects known as the Oort cloud.
A new class of exoplanet very different to our own, but which could support life, has been identified by astronomers, which could greatly accelerate the search for life outside our Solar System.
The asteroid, called 2021 PH27, completes an orbit around the sun every 113 days and comes within 12.4 million miles (20 million kilometers) of our star.
Two spacecraft are set to swoop past Venus within hours of each other this week, using the maneuver to do a little bit of bonus science on the way to their main missions at the center of our solar system.
The outskirts of our solar system is teeming with mysterious objects – and now one of them is heading our way. Astronomers have discovered a minor planet, 2014 UN271, that’s about to make its closest pass to the Sun on its 600,000-year orbit.
