We have been examining the recent discoveries of extrasolar planets – those planets that orbit a star other than the sun. Several thousand exoplanets have been discovered. In many instances, we know only the orbital period and minimum mass of the planet. In cases where the planet passes directly in front of its star, we are also able to estimate the size of the planet, its true mass, and therefore its density. But through some careful measurements and ingenious reasoning, there is additional information we can learn about exoplanets. And these new discoveries challenge the secular view of origins.

We have been examining extrasolar planets – planets that orbit a star other than the sun. The first exoplanets were discovered by measuring the slight wobble their gravity induces on their star. Amazingly, and despite the challenges involved, around 50 exoplanets have now been directly observed using powerful telescopes. But the majority of exoplanets have been discovered using the transit method. This technique, along with the others, has allowed us to discover nearly 5000 extrasolar planets.

Thirty years ago, the only known planets were those in our solar system. But now, astronomers have detected over 4,800 planets orbiting other stars in our galaxy. These extrasolar planets challenge secular origins scenarios and confirm biblical creation.
