![]() EST, followed by Io's tiny black shadow from 9:25 to 11:38 p.m. Then Jupiter's fastest big moon, Io, crosses Jupiter's face from 8:25 to 10:39 p.m. ■ Jupiter's Great Red Spot transits the planet's central meridian around 8:18 p.m. Also, see Roger Sinnott's Useful Projects for a Lunar Eclipse: "Here’s all you need to know to help us measure the size of Earth’s shadow during the second lunar eclipse of 2022." The first and last penumbral shading on the Moon may be detectable for 30 or 40 minutes before and after the partial stages - if the Moon is up at your location and the sky is not too bright.įor more info, a map, and a detailed timetable see Bob King's Last Total Lunar Eclipse Till 2025. Tuesday the 8th Eastern Standard Time (9:09 on the 8th UT) total eclipse begins 5:16 a.m. Timetable: Partial eclipse begins at 4:09 a.m. From Asia through Australia, the eclipse will be seen on Tuesday evening local date. The farther west you are, the higher the Moon will be and the longer the sky will remain fairly dark. ■ Total eclipse of the Moon before and/or during Tuesday dawn for most of North and Central America. Tuesday morning EST, about halfway between these two evenings for the time zones of the Americas. ■ Full Moon tonight and tomorrow evening. Jupiter and these three stars form a big right triangle. Look two or three fists right of Diphda and there's 1st-magnitude Fomalhaut, the Mouth of the Fish: the Alpha star of the Southern Fish, Piscis Austrinus. Almost halfway between them is fainter Iota Ceti, magnitude 3.5. This is Diphda (Beta Ceti), the Frog Star. Look below it by almost two fists for a 2nd-magnitude orange point. ■ Jupiter lights the southeast after dark. Clocks fall back an hour to standard time. Sunday morning for most of North America. How accurately can you time this event? Sextant not required. ![]() ■ Around 10 p.m., depending on where you live, zero-magnitude Capella rises exactly as high in the northeast as zero-magnitude Vega has sunk in the west-northwest. Jupiter is actually 40 times larger in diameter than the Moon, and it's currently 1,650 times farther away. The Moon shines with Jupiter Friday night the 4th, but looks are deceiving. Consider, as you look, that each of those four is roughly the size of our own Moon so much closer in the foreground. They're both prime targets for small telescopes! Most scopes will usually show at least the tan North and South Equatorial Belts on Jupiter's dazzling whiteness, and of course its own four big moons on either side of it (except when one of them is hidden behind Jupiter, passing in front of it, or eclipsed in its shadow). They're only about 2° to 4° apart at the times of evening in the Americas. The moon is more closely related to the planets than it is to the Sun, and since it only orbits the Earth, it is neither considered a star nor a planet.■ The waxing gibbous Moon shines with Jupiter this evening, as shown below. Interestingly, if the moon were not orbiting the Earth, it would likely be defined as a planet. In terms of composition, the moon is similar to the Earth in some ways. The debris from this collision entered into Earth’s orbit and eventually coalesced to form the moon. The moon formed around 4.5 billion years ago due to a collision between the Earth and another planet. Rather than being a planet or a star, the moon is a natural satellite that orbits the Earth. The Moon Is A Natural Satellite A view of the Earth and Moon in space. Therefore the moon is definitely not a star. The moon is nowhere near being massive enough for nuclear fusion to occur. Stars are different from planets in that they are mostly more massive, allowing atoms to fuse together and release energy. Nuclear fusion is a process by which hydrogen atoms are fused together to form helium, and it only happens when an object has enough mass. Is The Moon A Star? Night Sky with stars, moon, and clouds.Ī star is defined as an object whose mass is sufficient enough for the process of nuclear fusion to occur and be sustained. Therefore the moon is not defined as a planet. The moon revolves around the Earth only and not the Sun. In the case of Earth’s moon, it follows criteria number two and three, but it fails to meet the first criteria. If an object follows these three criteria, it is defined as a planet. The object must have a strong gravitational pull to clear its orbit of debris.Its gravity must be strong enough to make the object spherical.When we talk about some of these objects, most of us likely have good knowledge of what these objects are, but do we know what makes them different? In terms of the moon, why isn’t it a planet or a star? What Is A Planet? Solar System. In our solar system alone, there are many different objects such as the Sun, planets, asteroids, comets, meteorites, moons, dwarf planets, etc. The universe is home to a wide diversity of different objects.
