NOAA satellites have the capability to provide astounding views of the Earth. But many people want to know if these satellites can see their house, or even through their roofs and walls to the people inside. The answer is: no. Satellites differ greatly in the level of detail they can “see”.
The exact time of the passage this evening will start at 10.34pm as Starlink-5,6 passes across the sky. It should be visible for around six minutes. At present, there are 300 Starlink satellites in place with SpaceX eventually planning to put 12,000 in place.
Satellite watching is generally done with the naked eye or with the aid of binoculars since most low Earth orbit satellites move too quickly to be tracked easily by telescope. It is this movement, as the satellite tracks across the night sky, that makes them relatively easy to see.
SpaceX's Starlink satellites are visible across western Europe — here's why and how you can spot them flaring in the night sky. Elon Musk's space exploration company, SpaceX, plans to launch up to 42,000 satellites into orbit to beam internet down to remote parts of the Earth.
That means the light can't penetrate the cloud on the way down to earth, let alone penetrate the cloud on its way back up (satellites look down at angles ranging from 0-30 degrees) in order for the sensor to capture it. But, RADAR can see through clouds because the wavelengths are much shorter than visible light.
Surprisingly there are a large portion of manmade satellites that can be seen with the naked eye. Sightings can number up to a hundred in a single night if you have good viewing conditions. To identify a satellite you are looking for a star that looks like it is slowly moving across the night sky.
Ariane 5 – Largest-ever telecommunications satellite launched. Earlier this evening, an Ariane 5 ECA launcher lifted off from Europe's Spaceport in French Guiana on its mission to place the heaviest and most powerful telecommunications satellite ever launched, TerreStar 1, into geostationary transfer orbit.
As of 24 April 2020, 422 satellites were launched.
You can catch all 5 bright planets in May 2020. Use the waning moon to catch the morning planets – Jupiter, Saturn and Mars – from May 11 to 14, 2020. Read more. We expect Mercury, the innermost planet, to become visible by mid-May 2020, if not before.

We expect Mercury, the innermost planet, to become visible by mid-May 2020, if not before. Conveniently, dazzling Venus is there to help guide you to Mercury's location near the sunset point.
The five brightest planets - Mercury, Venus, Mars, Jupiter and Saturn - have been known since ancient times and can easily be seen with the naked eye if one knows when and where to look. They are visible for much of the year, except for short periods of time when they are too close to the Sun to observe.
Jupiter. Jupiter is currently in the constellation of Sagittarius. The current Right Ascension of Jupiter is 19h 55m 43s and the Declination is -20° 55' 29”. The current magnitude of Jupiter is -2.39 (JPL).
2011 November 26 – Disk 90% illuminated: Despite the fact that it appears impressive to the naked eye, Venus is not much to look at through a telescope. Still on the far side of the sun, at a distance of 136 million miles (219 million kilometers) from Earth, it appears a small, almost full silvery disk.

Venus will appear tonight in the western skies, shining brightly until about midnight.
Then it resumes its normal westward motion, and as Mercury moves farther from the Sun, the solar disk begins to shrink in size until sunset, 88 Earth days after sunrise. What a day! And then, for a period lasting 88 Earth days, it is night for you.
The surface gravity on Mercury is only about 38% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh only 38 pounds on Mercury.
But, at opportune times – like now, for the Northern Hemisphere – you can see Mercury fairly easily, if you go outside and look west after sunset. At present, Mercury is nearing the outer edge of its orbit, as seen from Earth.
When and where to look. Currently, Mercury is visible about 35 to 40 minutes after sunset, very near to the horizon, about 25 degrees south of due west. Your clenched fist held at arm's length measures roughly 10 degrees, so approximately 2.5 "fists" to the left of due west, along the horizon, will bring you to Mercury
Five planets can be recognized as planets from Earth with the naked eye: Mercury, Venus, Mars, Jupiter, and Saturn. Close to sunset and sunrise bright stars like Sirius or even Canopus can be spotted with the naked eye as long as one knows the exact position in which to look.
The stars twinkle in the night sky because of the effects of our atmosphere. When starlight enters our atmosphere it is affected by winds in the atmosphere and by areas with different temperatures and densities. This causes the light from the star to twinkle when seen from the ground.

Then, as dusk deepens into darkness, look for Mercury to pop out below Venus in the western sky. Mercury will be close to the sunset point on the horizon. You might see Mercury with the eye alone within an hour after sunset. With binoculars, you can spot Mercury (and Venus) even earlier.
Ultimately, as Venus prepares to pass between the Earth and the sun, it appears as a thinning crescent. Still on the far side of the sun, at a distance of 136 million miles (219 million kilometers) from Earth, it appears a small, almost full silvery disk.
The side of Mercury facing the sun is very hot, about 800° Fahrenheit! But the dark side gets very cold, about –280° Fahrenheit, with no sun to warm it and no atmosphere to hold in the heat.
How old would I be on Mercury?
The Days (And Years) Of Our Lives
| Planet | Rotation Period | Revolution Period |
|---|
| Venus | 243 days | 224.7 days |
| Earth | 0.99 days | 365.26 days |
| Mars | 1.03 days | 1.88 years |
| Jupiter | 0.41 days | 11.86 years |
Venus is sometimes called Earth's twin because Venus and Earth are almost the same size, have about the same mass (they weigh about the same), and have a very similar composition (are made of the same material). They are also neighboring planets. However, Venus and Earth are also very different.
Long Days, Short Years
One day on Mercury (the time it takes for Mercury to rotate or spin once with respect to the stars) takes 59 Earth days. One day-night cycle on Mercury takes 175.97 Earth days. Mercury makes a complete orbit around the Sun (a year in Mercury time) in just 88 Earth days.It would be a very long workday from an Earth perspective! This is because Mercury's rotation around its axis lasts 59 days, and it takes 88 days to move around its orbit around the Sun. In fact, such a day on Mercury is twice as long as a Mercurian "year" !
