<p>Jupiter and Venus are easily confused, since they can both appear to be bright and white. You really need to consider the time of day and the elevation (how high it is in the sky).

Venus can climb quite high in the sky, but it will never be more than 45° in elevation.</p>

"High in the sky" is not very reliable, though. It depends on your location and the planets declination. Saturn is really low now, for example, as seen from the northern hemisphere.

@EricDuminil For sure, but if it's high in the sky, it's unlikely to be Venus.

@Mick this week, venus is at 30° elevation, from my location, before sunrise. Jupiter and Saturn are close to 20° when they're highest in the sky, after sunset.

@EricDuminil Oh, well. I did say that they are very rough rules of thumb, and 30° elevation is not that high. I don't really want to grind the sausage too fine.

@Mick fair enough. You're right, 30° isn't very high, I'm just a bit frustrated to not live in the southern hemisphere right now. Another rule or thumb could be that if you see a planet at midnight, it's surely not Mercury or venus.

@EricDuminil You can see the sun at midnight, at an appropriate latitude and time of year, so you can certainly also see planets close to the sun.

@Ruslan I've already seen Mars, Jupiter, Saturn and Venus with my telescope in full daylight, using the moon as a guide when it passed close to the corresponding planets. It's surprisingly hard to find good rules of thumb in order to identify the planets.

To add to this answer: Mars is currently approaching opposition, so it's rising (brightly) soon after sunset. This week (October 6, 2020) it will be nearest to Earth (62m km), its closest approach until 2035. It reaches opposition (the point at which it falls along a line extending through the Earth and Sun) on October 13.

Thank you for including time and location info. I don't think that I shall see Mars tonight. The weather here is atrocious.

Stellarium shows the Moon and Mars very close together in the sky tonight (Saturday, 3rd October 2020), so yes, it was probably Mars that you saw.

[Moon and Mars on 2020/10/03 (Stellarium)](https://i.sstatic.net/KtrfX.jpg)

[Stellarium](http://stellarium.org/) is a great tool for identifying astronomical objects (and satellites), and is absolutely free.

Very rough rules of thumb for identifying planets by eye:

* Very bright, white, and low in the sky (early morning or evening): probably Venus (but might be Jupiter).
* Bright, white, and high up in the sky: probably Jupiter (unlikely to be Venus, which stays close to the Sun).
* Bright and red: probably Mars.
* Moderately bright and pinkish: probably Saturn.
* Faint, white, and low in the sky (early morning or evening): might be Mercury.
* If it scintillates (twinkles), then it's a star.

Jupiter and Venus are easily confused, since they can both appear to be bright and white. You really need to consider the time of day and the elevation (how high it is in the sky). Since Venus is closer to the Sun than the Earth, you are more likely to see it in the morning or evening (before sunrise or after sunset). Venus can climb quite high in the sky, but it will never be more than 45° in elevation.
