Perseverance mars rover caught UFO near the Sun

On March 7, 2021 the Perseverance mars rover took a remarkable image of the sun, (Sol 16) with its left navigation camera (Navcam) but surprisingly the image also shows an unknown object next to the sun.

Maybe a sungazing comet that passes extremely close to the Sun or... could it be that the rover captured a huge spacecraft? 

Suppose the object is not a comet, but artificial, then who designed this unidentified flying object capable of withstanding the extreme heat of the sun
