No. The inner edge of the Oort Cloud is 10 light days away. The outer edge of 100 ld away.

The math looks like:

• 1 AU is the distance from the Sun to Earth.
• The Earth is 8 light minutes from Sol
• The inner edge of the Oort Cloud is (minimum) 2,000 AU ≈ 16,000 light-minutes, or 11 day light days.
• The outer edge is about 100,000 AU away; that's about a year and a half to get from the inner edge to the outer edge, traveling at the speed of light.

The Oort Cloud is not only mind bogglingly far away, it's about 50x deeper than it is away from the sun.

Those are minimum estimates; some estimates have the inner cloud edge 28 AU away.

The original Superman wasn't a god, but it got hyperbolic over the years with one-upmanship until he was indistinguishable from a god. Canonically, beings regularly travel between star systems, so FTL is not uncommon in the DC universe. Heck, in Invincible (not DC), even relatively low-power beings travel FTL all over, all the time. Spacetime doesn't work the same in comics. So, Superman can travel FTL, and the Oort Cloud would be reachable. But he'd have to travel at least 20x the speed of light to get to the Cloud and back in a day, and thousands of times faster if he wants to explore it at all, or see the outer edge.
