faint

Not bright, so it is hard to see.

Used of light or something seen by its light, faint describes something that is present but not strong or clear, often because it is distant or weak.

• Even through the city haze, we could make out a faint star near the horizon.
• The telescope revealed a faint glow around the distant nebula.
• At first, the meteor shower looked faint, but more streaks appeared after midnight.
