Default Early next week, a large asteroid...

Space Weather News for Jan. 21, 2015
http://spaceweather.com


Early next week, a large asteroid named 2004 BL86 will fly past the
Earth-Moon system. There's no danger of a collision, but NASA radars
will be monitoring the mountain-sized space rock as it passes by only
745,000 miles away. Amateur astronomers can watch the flyby, too.
Glowing like a 9th magnitude star, 2004 BL86 will be an easy target
for backyard telescopes on the night of closest approach, Jan. 26-27.
Check http://spaceweather.com for observing tips and more
information.

Would that be an asteroid or a meteoroid? If it's not in the asteroid
belt, how is it an asteroid?

You didn't answer the question. Perhaps I didn't phrase it properly.
An asteroid is in the asteroid belt, a meteoroid is a drifting space
rock. Some asteroids have irregular orbits. so is this really an
asteroid or a meteoroid? The difference is in the orbit.

Not necessarily:
From the Wikipedia "Asteroid" article

"Terminology
Traditionally, small bodies orbiting the Sun were classified as
asteroids, comets or meteoroids, with anything smaller than ten metres
across being called a meteoroid. The term "asteroid" is ill-defined. It
never had a formal definition, with the broader term minor planet being
preferred by the International Astronomical Union."

Actually the PC term at the IAU is "dwarf planet" (which also includes comets?!) and anything "smaller" is called a "small Solar System body" (sSSb ?)

So strictly speaking, 2004 BL86 is a "dwarf planet," at least until the next IAU convention.

It should be visible in binos, but don't bother, because in order to "see it as it really is" you'll have to use a video cam or look at it on the Web, according to our resident troll, LsD.

Wikipedia is not always correct. (For example in one section Wik lists
25 time zones.) An asteroid by convention, is a piece of space junk
orbiting the sun, usually, but not always, found in the asteroid belt.
A meteoroid is a piece of space junk drifting in space with no defined
orbit. When such a meteoroid enters the atmosphere and burns up, it
is a meteor. When a meteor hits the ground it is a meteorite.

[NO OBJECT]
1Give out steady light without flame

If you are going to nitpick the meaning of words it's glowing, so it's
either a star or it's burning up in atmosphere 3/4 million miles away.

You wasted five minutes of my ****ing precious time with this post.
You didn't answer the question. I know the ****ing difference between
comets and asteroids. Do you know the ****ing difference between a
meteoroid and an asteroid? dumbass. Is this ****ing flying space rock
an asteroid or a meteoroid? you dumbass.
