Google's April Fool's Day tradition is called MentalPlex. It was introduced in 2000 as a hoax feature that claimed to use mental powers to predict search queries. This started Google's tradition of annual April Fool's pranks.

The first funding for Google came from Andy Bechtolsheim, co-founder of Sun Microsystems. He wrote a $100,000 check to 'Google Inc.' in 1998 before the company was even formally incorporated, making him Google's first investor.

Venus has no natural satellites or moons. It's one of only two planets in our solar system with no moons, along with Mercury. The claimed answer is correct.

Venus has the hottest surface temperature due to its thick atmosphere and extreme greenhouse effect. Despite Mercury being closer to the Sun, Venus reaches about 465°C. The claimed answer is correct.

Jupiter has the most moons with over 90 known satellites, including the four large Galilean moons. Saturn recently surpassed Jupiter in confirmed count but Jupiter still traditionally holds this title in many contexts. The claimed answer is correct.

Pluto's largest moon Charon is about half Pluto's diameter, making them the closest to being a double planet system in our solar system. Earth's moon is only about 27% of Earth's size, while Mars' two moons are much smaller tiny rocks captured by its gravity.

Triton, Neptune's largest moon, is the coldest object in the solar system at temperatures around -235°C. It's even colder than Pluto because Triton has a highly reflective surface that reflects most sunlight back into space, and it has a thin nitrogen atmosphere that contributes to heat loss.

Titan, Saturn's largest moon, is the only moon in our solar system with a substantial atmosphere - thicker than Earth's. Its atmosphere is mostly nitrogen with methane and ethane, creating a thick orange haze that hides the surface from view.

Uranus has an extreme axial tilt of about 98°, meaning it essentially rolls around its orbit on its side. This unique tilt was likely caused by a massive collision early in the solar system's history, and it results in extreme seasonal variations where each pole gets 42 years of continuous sunlight then darkness.
