History:
(
Uncanny Tales I#20 (fb) - BTS) - On Earth, it was discovered that Earth's moon was moving closer to the planet at a rate of 2 miles per day, and that it would accelerate the closer it got until the two bodies collided. Nel Ostron correctly posited that there was a planet ("Planet X") orbiting the sun exactly opposite (180 degrees around) to Earth, and that it was the cause of the attraction between Earth and the moon. While no one else believed him, Ostron was certain, and he believed that world must be destroyed or Earth would perish. Building a rocket, Ostron took to space.

(Uncanny Tales I#20 (fb) - BTS) - At some, an astronomer on "Planet X" realized that their moon was moving closer to their world at a rate of 1 mile per day.

(Uncanny Tales I#20) - Ostron spotted "Planet X" and traveled there, hoping he could find a solution to Earth's danger once he landed.

    Landing undiscovered at night time, Ostron confirmed that there was not any dangerous radioactivity and that the world's atmosphere was chemically identical to Earth's. Exiting his rocket, he found the ground to be the same as Earth's and, seeing lights, he realized there must be life on this world. Rushing toward the lights, he was surprised to find a city just like that of Earth's, and he concluded that Earth had been duplicated. planetx-54561-astronomersinostronsship

    Ostron entered an astronomers convention where an astronomer announced confirmation that their moon was approaching their world at 1 mile/day, and Ostron realized that this world faced a similar threat but at a reduced rate. Ostron interrupted the speaker, noting a planet opposite their world around the sun to be the cause. Ostron's argument was considered preposterous by those present, disbelieving Ostron when he told them that he had come from that other world. They agreed to accompany him to see his space ship, but the astronomers of Planet X felt that someone could have made a space ship as many people had been trying to build one but they continued to discount his story; they further found that there was nothing about his ship that could not have come from their world.

    Arguing that one of their two worlds would have to be destroyed and acknowledging that they would need proof positive before they would even consider options to resolve the situation, Ostron insisted that two people from Planet X accompany him in his ship to see his world. After lots were drawn, two skeptical scientists were selected, and they entered Ostron's ship; after they departed their world, the scientists congratulated Ostron for making their world's first space ship, but they told him he had not needed to tell them the lie about his planet to get them there.

    As they reached the point where they could see Earth, however, the scientists from Planet X exclaimed that they had been right, and Ostron shocked to look out a view port and see only smashed chunks of Earth and the moon, and he realized that they had been too late.

    I would assume the implication would be that since Earth and its moon were destroyed, Planet X and its moon were no longer being pulled together.

    I'm not sure how a planet on the opposite side of the sun would cause an attaction between Earth and its moon. Plus, presumably this world did not just appear there and had been in existence as long as Earth, so why was it suddenly affecting Earth's moon?
    ...but it is 1950s Sci-Fi...what do you want for nothing?

    Math during cocktail hour is not the best idea, but per lazy internet research:
    The distance of Earth's orbit is about 150 million miles, so something halfway around the sun would be 75 million miles (120 million kilometers). Earth orbits the sun around 18.75 miles per second (30 km/second), and modern rockets in space (like Juno), travel at a little under twice that speed (36.25 miles/second or 58 km/second). Assuming Ostron had the sense to travel opposite of the orbital direction, this would combine the speeds to bring him closer to Planet X at 55 miles/second or 88 km/second, which would take about 1,363,636 seconds = 22,727 minutes = 378 hours = about a year and 13 hours.
    Ostron noted that his ship had acheived greater than 7 miles/second, which I believe is good for escape velocity, but then after escaping Earth's atmosphere, he notes that in 8 seconds he would be in a position to see around the sun and spot the world on its opposite side. I don't have the knowledge to know how far around he would have to be to see that world, but I would think it would be well over half the distance, so like 40 million miles in 8 seconds...that seems pretty excessive to me.
    Not sure why I spent the time time figuring all of that out....

    If the Earth was moving closer at a rate of 2 miles/day, since the moon is about 250,000 miles from Earth, it would have taken 125,000 days or 342 years for the moon to strike Earth. However, they did note that things would speed up as they got closer, so perhaps it happened much more quickly than would have been expected (plus, we don't know how long this had been going on before it was discovered).

    Nels Ostron and his ship can get their own profile at some point. If someone wants to do that, I would strongly encourage a separate profile, rather than just adding sub-profiles on characters not from Planet X to a profile on Planet X.

(Uncanny Tales I#20) - At an astronomer's convention, an astronomer announced confirmation that their moon was approaching their world at 1 mile/day. Having traveled there from Earth, Ostron interrupted the speaker, noting a planet opposite their world around the sun to be the cause. Ostron's argument was considered preposterous by those present, disbelieving Ostron even when he told them that he had come from that other world.

     They agreed to accompany him to see his space ship, but the astronomers of Planet X felt that someone could have made a space ship as many people had been trying to build one but they continued to discount his story; they further found that there was nothing about his ship that could not have come from their world.

    Arguing that one of their two worlds would have to be destroyed and acknowledging that they would need proof positive before they would even consider options to resolve the situation, Ostron insisted that a pair of people from Planet X accompany him in his ship to see his world. After lots were drawn, two skeptical scientists were selected, and they entered Ostron's ship; after they departed their world, the scientists congratulated Ostron for making their world's first space ship, but they told him he had not needed to tell them the lie about his planet to get them there.

Note: None of the astronomers were identified by name.

     The prominent figure with black hair is Nels Ostron, who traveled to Planet X from Earth.
