Wouldn't a small piece of a neutron star quickly explode via beta decay?

I would say if this is something exotic it may be a piece of neutron
star. Neutron stars are largely a neutron liquid of sorts. When they
collide this splash may hurl pieces of neutron liquid the size of a
baseball on up. This baseball sized piece of neutron liquid would have
the mass of our moon. These objects may be more common that we might
suppose.

Due to the odd orbits of recently discovered Trans-Neptunian
objects astronomers say that, unless it's just a very unlikely
coincidence, there is probably a unknown planet between 5 and 15
earth masses orbiting the sun between 300 and 1000 times as
distant from the sun as earth's orbit is, but other than this
indirect evidence optical telescopes have been unable to find the
slightest trace of it. A new paper suggests that the reason it's
so hard to find is that the gravitational mass may not be a planet
at all but is a Primordial Black Hole about the size of your fist,
and says we need to look for it with a Gamma Ray Telescope not the
optical sort.
What if Planet 9 is a Primordial Black Hole?
<https://arxiv.org/pdf/1909.11090.pdf>
The Optical Gravitational Lensing Experiment has detected ultra
short micro lezing events caused by gravitational masses in the
same range in the distant Magellanic Cloud (a dwarf galaxy)that
they assume were caused by free floating planets not connected to
any star, but perhaps it was caused by something even more exotic
like a Primordial Black Hole.

It's probably just a boring planet but maybe not, it would be
GREAT if it turned out to be true, we could actually sent a robot
spacecraft to explore a BlacK Hole, and if it used the sun grazing
"Goddard orbit" to boost its speed it could get there in less than
a decade.
