Planet Parade Syzygy

Just before sunrise Monday morning, June 3, 2024, six planets and an asteroid will form a “planet parade.” That means they will appear in a straight line as viewed from Earth. The planets involved are Mercury, Jupiter, Uranus, an asteroid, Mars, Neptune, and Saturn, going from the horizon up. Understand that is how we see them from Earth because Mercury and Jupiter are nowhere near each other.

With the naked eye, you should be able to see Mars, Saturn, and Jupiter, with Jupiter being the brightest. With binoculars, you might be able to see Uranus. With a telescope and knowing where to look, you will see all seven; if the sky is clear, you are away from light pollution and have a clear view of the eastern horizon. However, a crescent moon will make viewing a little more difficult. By Thursday, the Moon will be out of the way to better view the planets, but Mercury and Jupiter will have switched places. The change of position will be caused by the outer planets (Jupiter) appearing to move more slowly than the inner planets (Mercury).

The planets’ ability to appear close together in the sky shows how flat our solar system is. In other words, the planets orbit the Sun in nearly the same plane rather than in random directions. That fact allows the outer planets, especially Jupiter, to serve as comet sweepers, protecting Earth from dangerous objects coming in from beyond the solar system.

A syzygy is a true alignment of planets, which happens very rarely. This planet parade is an interesting apparent alignment, and “syzygy” is a good word to remember the next time you play Scrabble. This beautiful view of our solar system reminds us of God’s wise artistic and engineering design.

Jupiter Is in Opposition

June 10, 2019, is an excellent time to observe the largest planet in our solar system. The reason is that Jupiter is in opposition to our Sun.

When astronomers say that Jupiter is in opposition, they mean that planet Earth is passing between the Sun and Jupiter. At this time, Jupiter will rise in the east as the Sun sets in the west, and it will set in the west as the Sun rises in the east. In other words, Jupiter will be visible all night long, and it will be at its highest point in the sky in the middle of the night.

The picture was taken by the JunoCam on NASA’s spacecraft Juno which is currently orbiting Jupiter. NASA posts the raw images online and encourages individuals to download and process them. Citizen scientist Kevin M. Gill enhanced this one. You can find access to the raw images and see the work of other citizen scientists by clicking HERE.

When you see Jupiter in the sky tonight, it will not look like this picture, but it will be the brightest object in the sky. Jupiter is not a rocky planet like Earth. It’s a gas giant which if were 80 times more massive, would be hot enough to set off nuclear reactions in its core. Then it would be a star giving off its own light instead of just reflecting the Sun’s light. However, if you could lump all the other planets in our solar system together (including Earth), Jupiter would be 2.5 times more massive than them all.

Why do we need such a huge gas giant in the outer solar system? As we have said in previous posts, Jupiter is a comet sweeper. With its massive size and gravity, Jupiter protects us from objects such as comets coming from outside our solar system. In the 1990s, NASA observed Jupiter pulling apart and destroying comet Shoemaker-Levy 9. You can read about that in our previous post HERE. Jupiter also affects Earth’s climate cycles, which you can read about HERE.

Jupiter is in opposition about every 13 months. Last year opposition occurred in May. Next year it will be on July 14. If you miss seeing Jupiter tonight because of cloudy weather or any other reason, don’t despair. Jupiter will be closest to Earth on June 12, and it will continue to be visible, but right now it’s visible all night long.

While Jupiter is in opposition, or at any other time, look up and thank God that He has created such a marvelous and unique solar system to make life possible.

Jupiter Comet Shield

There is a significant amount of debris left over from the formation of the solar system existing in clouds outside the solar system. That debris eventually gets attracted toward the Sun. In 1992 scientists observed Jupiter pulling the comet Shoemaker-Levy 9 apart and breaking it into more than 20 pieces which eventually slammed into Jupiter’ surface in 1994. We learned that we have a Jupiter comet shield to protect our planet.

It is obvious that Jupiter is essential to the survival of life on Earth if for no other reason than the shield it gives us. Right now a spacecraft named Juno is orbiting Jupiter and sending back data and pictures that are amazing. The spacecraft has made five elliptical orbits since last July dipping to within 2100 miles of Jupiter’s atmosphere, collecting data, and taking photographs. ScienceNews.org has some of the amazing pictures.

Here are some things we have learned about Jupiter:

*Polar cyclones 900 miles wide circle the planet.

*Jupiter has a powerful magnetic field about ten times stronger than Earth’s.

*Powerful auroras work in the polar areas of the planet but are different from what we observe on Earth in both structure and function.

*There is a concentrated band of ammonia near the planet’s equator.

There is still much to learn about this giant planet. The observations we are making assist us in understanding how the solar system was formed. They also show us what affect Jupiter has on us today as well as in the future. Psalms 19:1 tells us that “The Heavens declare the Glory of God and the firmament shows his handiwork.” It is an exciting time to be alive and to watch as we use new tools to understand the creation and how God has given us a Jupiter comet shield.
