In classical antiquity, the seven classical planets or seven luminaries are the seven moving astronomical objects in the sky visible to the naked eye: the Moon, Mercury, Venus, the Sun, Mars, Jupiter, and Saturn.
Australians will be able to see Jupiter, Mercury, Venus, Uranus and Mars.
Mercury, Venus, Mars, Jupiter and Saturn are all currently visible simultaneously with the naked eye. The two outermost planets, Uranus and Neptune, can meanwhile be observed with binoculars or a telescope.
Saturn is the sixth planet from the Sun, and the second largest, after Jupiter. It is one of the five planets visible from Earth using only the naked-eye (the others are Mercury, Venus, Mars and Jupiter).
Mercury, Venus, Mars, Jupiter, and Saturn are the five brightest planets in our night sky and, therefore, observable by most people.
The planet Saturn: truly massive and stunningly beautiful with its rings. It's also home to amazing moons like Titan. The planet Saturn is probably the best known and most beautiful planet in the Solar System.
Venus: Brightest planet. Venus is the brightest planet we can see from Earth. It outshines all the stars. When it's close to the horizon (which it often is, being closer to the sun than Earth), people frequently mistake it for a plane with its landing lights on.
Difficult to observe
Out of the five planets known since ancient times as the 'wandering stars', Mercury is the one least explored. Unlike Venus, Mars, Jupiter and Saturn, Mercury is notoriously difficult to observe from Earth. Being the innermost planet of the Solar System, it always appears too close to the Sun.
Venus can often be seen within a few hours after sunset or before sunrise as the brightest object in the sky (other than the moon). It looks like a very bright star. Venus is the brightest planet in the Solar System.

Dark, cold, and whipped by supersonic winds, ice giant Neptune is the eighth and most distant planet in our solar system. More than 30 times as far from the Sun as Earth, Neptune is the only planet in our solar system not visible to the naked eye.
There is a lot of evidence for the planet – thought to be up to 20 times further out from the Sun than Neptune – but it may be impossible to see with current technology. The giant, hidden planet is thought to be 10 times larger than Earth and on an orbit that takes 10,000 or 20,000 years to go round the sun.
Overview. Caltech researchers have found mathematical evidence suggesting there may be a "Planet X" deep in the solar system. This hypothetical Neptune-sized planet orbits our Sun in a highly elongated orbit far beyond Pluto.
Sirius is the brightest star in the night sky. UPDATE: This article was published in January 2022—if you're reading this in August/September 2022 then here's what you need to know about the very bright “star” in the east after dark.
AFTER SUNDOWN FROM late July through August, there's the chance to see five planets at once in the evening sky. Mercury, Venus, Mars, Jupiter and Saturn are the only planets in our solar system bright enough to be seen with the naked eye.
Uranus holds the record for the coldest temperature ever measured in the Solar System: a very chilly -224℃. The temperature on Neptune is still very cold, of course – usually around -214℃ – but Uranus beats that. The reason why Uranus is so cold is nothing to do with its distance from the Sun.
Venus is the brightest, brighter than any star and sometimes visible in the daytime (if you know where to look). Jupiter is also brighter than any star, while Mars is quite variable, sometimes as bright as Jupiter and sometimes only a little brighter than the North Star.
Jupiter is currently in the constellation of Pisces. The current Right Ascension is 01h 44m 19s and the Declination is +09° 39' 00”.
Uranus cannot be seen with our naked eyes. Uranus is the seventh planet of the solar system. It can be viewed only with the help of telescope.
It would not be possible for us to walk on the gas giants like Jupiter and Saturn, or in the ice giants like Neptune and Uranus because they are made of gas.
Mars has liquid water, a habitable temperature and a bit of an atmosphere that can help protect humans from cosmic and solar radiation. The gravity of Mars is 38% that of the Earth.
Kepler-452b (sometimes quoted to be an Earth 2.0 or Earth's Cousin based on its characteristics; also known by its Kepler Object of Interest designation KOI-7016.01) is a super-Earth exoplanet orbiting within the inner edge of the habitable zone of the sun-like star Kepler-452 and is the only planet in the system ...
Named GJ 504b, the planet is made of pink gas. It's similar to Jupiter, a giant gas planet in our own solar system. But GJ 504b is four times more massive. At 460°F, it's the temperature of a hot oven, and it's the planet's intense heat that causes it to glow.
