Released on March 8, 2025 by Tinkercast | Wondery

Introduction to "Wee Wow on the Weekend"

The episode kicks off with Dennis and his co-host, Reggie the giant pigeon, introducing "Wee Wow on the Weekend," a playful segment where they engage in humorous antics and share snippets from other Tinkercast podcasts. Dennis sets a lighthearted tone, emphasizing fun and camaraderie.

Dennis ([02:07]): "We wow on the weekend. Cause this is what we do on the weekend. Talking, laughing. Me and Reggie singing, laughing."

Main Adventure: Journey to the Asteroid Belt

Setting Off with the "Wow Machine"

Dennis and Reggie embark on an interstellar adventure using their time-traveling vehicle, the "Wow Machine," renamed and freshly painted by Mindy. Their mission is to explore the asteroid belt, located between Mars and Jupiter.

Guy Raz ([13:01]): "No time to waste."

Mindy ([15:32]): "Lucky for us, we have an almost fully functional wow machine that can zip us from here to there in no time at all."

Encounter with Various Asteroids

As they navigate the vast expanse of the asteroid belt, the hosts encounter different types of asteroids, each with unique characteristics.

1. M-Type Asteroids (Metallic)

   Guy Raz explains that M-type asteroids are composed primarily of nickel and iron, making them one of the rarer types.

   Guy Raz ([17:09]): "An M type asteroid. ... It's a mix of nickel and iron, to be precise."

2. C-Type Asteroids (Carbon)

   These asteroids are predominantly carbon-based and are nearly pitch black, comprising about 75% of the belt.

   Guy Raz ([18:08]): "They're carbon, Mindy. The C stands for carbon in C type asteroids."

   Mindy ([19:00]): "Luckily it's not completely pitch black. We would have run straight into it."

3. S-Type Asteroids (Silicaceous)

   Silicaceous asteroids contain magnesium silicates in addition to nickel and iron, accounting for approximately 17% of the asteroid belt.

   Guy Raz ([20:35]): "Kiss Silicaceous. They're similar to the metallic asteroids... they have lots of other types of metal in them, like magnesium silicates."

Discovery of Ceres, the Dwarf Planet

The team spots Ceres, the largest object in the asteroid belt, classified as a dwarf planet. Guy Raz highlights its unique composition, including a crusty layer of ice.

Guy Raz ([19:11]): "What we're looking at is Ceres, the 590 mile wide dwarf planet."

Mindy ([19:23]): "So what else is it made of?"

Guy Raz ([19:25]): "It's got a nice crusty layer of ice that covers its surface."

Understanding Orbits: Prograde and Retrograde

Mindy and Guy Raz delve into the dynamics of asteroid orbits, distinguishing between prograde (forward) and retrograde (backward) orbits. They elucidate how most celestial bodies orbit and spin in the same direction, maintaining a harmonious cosmic flow.

Mindy ([21:19]): "And in the world of astronomy... that's called a prograde orbit."

Guy Raz ([21:26]): "Meaning that they all move in the same direction."

Mindy ([21:33]): "Ooh la la. Well, look at you, you little cerebrumarca."

Guy Raz ([21:46]): "That's wild, Mindy. So what you're saying is if we keep following these asteroids in a clockwise direction around the sun, we should be completely safe?"

Encounter with the Retrograde Asteroid BZ509

The adventure takes a tense turn when Dennis alerts the team about an incoming asteroid. Initially believing it's a minor pebble, they soon realize it's BZ509, an intergalactic visitor traveling in a retrograde orbit—opposite to the usual direction.

Guy Raz ([23:26]): "Meteor Impact in 10, 9, 8..."

Mindy ([24:08]): "This is the intergalactic guest I was telling you about before."

Guy Raz ([23:50]): "BZ. Huh. Well, besides the fact that it's traveling in the wrong direction, it really doesn't seem all that alien."

Scientific Insight:

Guy Raz elaborates on the significance of BZ509's retrograde orbit, indicating its extraterrestrial origin. Collaborations between scientists Dr. Fatina Mooney and Dr. Helena Marais revealed that BZ509 has been in our solar system since its formation, suggesting it originated from another part of the universe.

Guy Raz ([25:03]): "They found that even when they rewound the simulation all the way back to the beginning of our solar system... BZ was still orbiting around the sun in the wrong direction."

Mindy ([25:42]): "So this interstellar visitor has just been hanging out in our solar system for billions of years?"

Guy Raz ([26:05]): "It sure seems that way, Mindy."

Conclusion: Return to Earth and Pancake Party

Realizing the potential threat of BZ509, Dennis and Reggie’s adventure concludes as they decide to return to Earth. Upon their return, they find their home, the gingerbread mansion, miraculously cleaned and ready for a pancake party hosted by Maggie the Magpie. The episode wraps up with light-hearted banter and reflections on their cosmic journey.

Mindy ([27:16]): "Buckle up. Okay, here we go. Ah, mansion. Sweet gingerbread mansion."

Mindy ([28:09]): "I'd love to."

Dennis ([28:12]): "Wow, that was so cool... Silica ceous. That's good. I don't like asparagus."

Hosts' Reflections and Closing Remarks

Dennis humorously summarizes the adventure, highlighting the different asteroid types, albeit with a playful misstatement.

Dennis ([28:43]): "And what were the types again? Metal, carbon and asparagus. Right, right, right, right. Silica ceous."

The episode concludes with promotional messages encouraging listeners to engage with the podcast on various platforms, emphasizing early and ad-free access through Wondery services.

Mindy ([29:27]): "If you like wow in the world, you can listen early and ad free right now on Wondery."

Guy Raz ([29:43]): "Tell us about yourself by filling out a short survey@wondery.com survey."
