Tiny Planet

Tiny Planet is a passive item.

Effects

 * Range greatly increased.
 * +7 Shot Height, allowing tears to fly over all obstacles.
 * Tears now revolve around Isaac at a fixed distance until they hit the ground.

Interactions

 * A Lump of Coal - This item drastically increases the screen time of tears because it makes them orbit around Isaac for a few seconds. A Lump Of Coal adds a lot of damage to tears in "outer orbit".
 * Anti-Gravity - Tears remain stationary until released, then snap back into orbit.
 * Azazel Brimstone - Increases Azazel's range with Brimstone, and warps the beam around the character.
 * Bob's Rotten Head - The thrown bomb orbits Isaac, making it hard to predict where it will land.
 * Brimstone - The beam will wrap around the character and shoot straight forward.
 * Dr. Fetus - Tears turns to bomb that orbit very fast around Isaac and explode after a short time.
 * Hook Worm - Has no effect.
 * Ipecac - Explosive tears orbit around Isaac.
 * Marked - You will continuously fire orbiting tears, which allows you to not touch the attack keys and focus just on moving (with giant tears it makes it hard to see as you can't stop firing).
 * Mom's Knife - The knife will spiral out clockwise from where it is held, and then return along the same path. The distance that it moves is proportional to how long the throw is charged, as per usual. This makes the knife much more difficult to use effectively.
 * Monstro's Lung - This item removes the extra height and range bonuses, causing the burst of tears to circle around and land behind the player after only being airborne for a short time.
 * My Reflection - Tears will move to maintain their orbital positions around Isaac as he moves, making aiming much easier.
 * Ring Worm - Every single tear spins uncontrollably fast, making aiming incredibly difficult. However, with large shots (Death's Touch with high damage, for instance) this combo can fill the entire screen with projectiles almost immediately.
 * Rubber Cement - Tears bounce off enemies then keep orbiting Isaac. Very powerful as the tears are not destroyed upon damaging an enemy. When near walls, the orbiting tears have a tendency to get stuck against the walls until Isaac moves away.
 * Sad Bombs - Tear shots from bombs will circle around the bomb, giving increased hit chance.
 * Spoon Bender - The tears still revolve around Isaac's body, but now home in on enemies.
 * Tammy's Head - The tears orbit around Isaac, making it easier to hit enemies.
 * Technology - A laser creates a circle around Isaac's body before being fired forward normally.
 * Tractor Beam - Tears no longer orbit Isaac and will instead travel along the beam.
 * Tractor Beam + Rubber Cement - Tears will travel along the beam until they hit a wall and then orbit Isaac.
 * The Ludovico Technique - The tear controls strangely. It orbits Isaac slowly when not controlled, and when controlled, the tear's movement is distorted.
 * Wiggle Worm - The tear forcefully orbits while spiraling. The orbit amplifies the wiggle.
 * Lost Contact - Shielded tears will orbit Isaac, granting a partially successful 360 degree projectile protection around him. Works better with faster fire rate.

Trivia

 * Tiny Planet was considered as a cosmetic item in Team Fortress 2, alongside Skatole, tears, and Brimstone.
 * This item is used in Challenge #3 (Head Trauma).
 * The item is likely a reference to asteroids.
