Did somebody order a mentos? This is called "Sol Gate" and is an asteroid (or is classified as such) within our solar system. Not sure if this is a glitch or what but it just looks like a giant mentos
Oops my mistake, I forget to put the texture Stargate.png. I fixed.
Otherwise
Gate (Sol Gate in example) isn't a asteroid. It is a spacecraft but in planet's catalogs, I put asteroid.
