Precise observations made with NASA's Hubble telescope confirm that the interstellar interloper turns out to be the closest neutron star ever seen. Now located 200 light-years away in the southern constellation Corona Australis, it will swing by Earth at a safe distance of 170 light-years in about 300,000 years.

Are there any neutron stars in the night sky?
There are thought to be around one billion neutron stars in the Milky Way, and at a minimum several hundred million, a figure obtained by estimating the number of stars that have undergone supernova explosions.
Where is neutron star found?
Since neutron stars began their existence as stars, they are found scattered throughout the galaxy in the same places where we find stars. And like stars, they can be found by themselves or in binary systems with a companion. Many neutron stars are likely undetectable because they simply do not emit enough radiation.
What type of star is a neutron star?
neutron star, any of a class of extremely dense, compact stars thought to be composed primarily of neutrons. Neutron stars are typically about 20 km (12 miles) in diameter. Their masses range between 1.18 and 1.97 times that of the Sun, but most are 1.35 times that of the Sun.
Is there a neutron star on Earth?
Only about 1,000 pulsars are known to exist, though there may be hundreds of millions of old neutron stars in the galaxy. The staggering pressures that exist at the core of neutron stars may be like those that existed at the time of the big bang, but these states cannot be simulated on Earth.
What is the closest neutron star to us?
Precise observations made with NASA's Hubble telescope confirm that the interstellar interloper turns out to be the closest neutron star ever seen. Now located 200 light-years away in the southern constellation Corona Australis, it will swing by Earth at a safe distance of 170 light-years in about 300,000 years.
Will the sun become a neutron star?
Our Sun will never become a neutron star. Why? Because neutron stars are born from suns that are 10-20 times the size of ours. In 5 billion years our Sun will become a red giant and then eventually a cold white dwarf which is similar to a neutron star, just much larger and much less dense.
Is a pulsar a neutron star?
Pulsars and magnetars are both types of neutron stars, which are basically the cores of giant stars left over when the stars themselves go kablooie in events called supernovae.
Are neutron stars visible?
Neutron Stars are generally too hot for us to see. If one was to cool down significantly, to maybe 10 or 20 thousand degrees on the surface, then it might glow visibly blue and look like the brightest star in the sky, still just a point in the sky, but the brighest point in the sky at 1 AU.
Will the Sun become a neutron star?
Our Sun will never become a neutron star. Why? Because neutron stars are born from suns that are 10-20 times the size of ours. In 5 billion years our Sun will become a red giant and then eventually a cold white dwarf which is similar to a neutron star, just much larger and much less dense.
